Just subscribed. FINALLY found something worth paying for premium! Great, thoughtful "This is what you HAVE to do to coreectly diagnose problems, as opposed to throwing popular parts at the "problem".
Really appreciate this comment my friend. Looking forward to your comments and questions on the classes! And watching you progress in this field because of it!
Caleb is a lucky young man. I think I learned 55 things from this video aside from a faulty clutch. Really good stuff. One of the best I've seen on this platform, no kidding.
This dude should be more than a car mechanic. Not saying there's anything wrong with being a car mechanic,.. but clearly he can apply himself in a much larger capacity! Great video, and great information.
No, it’s great to have someone capable of proper diagnosis and not just someone who reads a code or changes parts until the problem goes away. Many of todays “mechanics” guess until the problem goes away, costing the customer much unnecessary expense.
The only thing I can tell you is thank you for not being selfish and teaching what you know to those who follow you. Believe me, people who help someone do well in life.
If you’re not a member you’re missing out… If you’re a technician, this is a must. Don’t be a parts changer… we’ve all heard that, but that’s the Motto here and the standard…. The best part is the explanation behind every diagnosis and it’s simplified plus VERY DETAILED ON THE PREMIUM CHANNEL. some times over the top which is the BEST. I’ve worked at shops that just change parts, with no reason and sometimes got it right but couldn’t explain why . I HATE THAT!! I love confidence and knowledge. This is the place, I’m never leaving thank you DANNER!!
Hi, Can someone help me? So I vacuum down the AC system and left it connect for a day and it seem to have lost 8psi (-22psi). I think it's a very slow leak since when I tested the system before Vaccum and it had a little pressure in it. So my question is if I inject the dye and then vacuum the system to load the Freon will it remove the dye from the system? Thx
This video just reaffirmed what I thought about one of my own cars. I love these videos so much I just watch for the fun and knowledge I gain. Been a mobile mechanic since 2008 but you learn something new everyday. Thanks for the opportunity to watch such informative videos with vast knowledge.
I knew nothing about fixing cars, just 6 months watching you , I can fix a good party of my car issue, I do understand everything perfectly even if I'm not too good in English. But my obsession is troubleshooting wiring, as one of the best car electrician. Reading wiring diagrams, fixing any issue wiring so replace the box fuses and redoing the wiring. Thank you Scanner Danner.
You explained everything so thoroughly that a 55 yr. old woman like myself can follow along with how you diagnosed & pinpointed the problem. I have a/c issues & have been educating myself *before* taking my truck to the garage. At first I thought I just needed a recharge, but sadly it's looking more like a clutch/compressor. Oh well, at least now I won't be surprised. THANKS - Jax., FL.
This morning 13/08/2019. I was doing my air conditioning and F.GAS training at the Birmingham city collage UK, it's pleasure watching you and I thank you from the bottom of my heart I learned a lot-off from you pleas don't stop making this videos
My favorite video on youtube is about a old piano being restored piece by piece by hand. Honestly; this comes in a close 2nd. Well done. Almost came in 1st place. Bravo.
That's awesome, I'm really glad you liked it. I've gotten the opposite reactions on this video too lol. From the silver bullet seekers (the ones who just want the fix and don't care to learn)
Awesome video professor. That key word "VARIABLE" is what haunts me in my head everytime I am about to make a call. That key word is what's transforming me as very well competent tech. That key word, once u are aware of the variables of the systems u are working with will prevent little to no comebacks. Thanx professor for all u taught us. Take care.😎
You are so what I need in my life. I have asked for a teacher that could explain things where I could understand what is going on. I just got my compressor changed in my car. And as soon as I did my water pump started to go bad. Then my car would not start, so I had to get a new battery. Then the battery light would not go off and I was told I need a new alternator. It has been a domino effect with the issues in my car and the mechanic I have can not explain anything except that the part is bad. I don't mind paying money as long as I can learn something in the process. I know that everything I attract is a lesson for me to learn. Now I have attracted you, a teacher that can help me understand these attractions so I can better my situations in life. I love the way you explain using visuals and in multiple scenarios . Your teaching skill is that of a master. I plan to join the Scannerdanner Premium classes so I can get more of your teachings. I can see you wholeheartedly love what you do and I appreciate you for that.
Great job and explanation. The pressure/temperature relationship was good as pv/t = pv/t (Charles and Boyles law works) and I especially liked the use of the relay tester as well as continuity checks. Your vocation is not in auto mechanics but rather should be in teaching practical sciences or a vocational technical school, but the pay is poor. I use the emergency brake in addition to chocks and leave the wedding band off while working. You enlightened me and I appreciate the effort.
Scanner Danner premium changed my life and the way I diagnose... Highly recommend this to anyone that has a passion for the trade and would like to better your knowledge.
Very nice example!! Even Caleb is picking up the material!! This is so difficult to understand, and how it all works!! When I was a teen, a A/C tech neighbor had retired, but was still doing service calls, and used me as a helper. He tried to teach a young teen, some basic info, and he couldn't break thru!! I just couldn't understand it, and wouldn't listen! I went a different way! The hardest part for me, was understanding the idea that refrigerant boiled at -40 degrees!! I knew that water boils at 212 deg, so how could refrigerant be hot enough to cook pasta at -40, and how did that make me feel cold!! My weak brain couldn't get he idea! It just held me back for so long! It wasn't until I learned the basic principles of science, how it all worked! For me, it was the realization of what "BOILS" means!! Basic science! Boils means CHANGE FROM A LIQUID STATE TO A VAPOR STATE!! It doesn't mean that it will make pasta for us!! And when it changes,(BOILS) it absorbs heat!! So, the point that refrigerant boils, it absorbs the surrounding heat, and makes things around it feel cool (or scientifically, the absence of heat)! The rest I could fit together, and it all made sense to me!! The A/C system is just a controlled compression and then release of a material that helps absorb the excess heat, to make us feel good!! Great job, Scan!! And Caleb too! Thanks for sharing!! AND TEACHING!! AND ENTERTAINING!!
Yeah, and when the refrigerant level gets so low you hear the expansion device hiss behind the dash almost like a gas stove would, you don't get cold air anymore because liquid->vapor transition isn't happening anymore.
Excellent info! I loved the pressure readings explanation with regard to air temps. The $11 that I pay for SD Premium is well worth it. This past Saturday I saved a good $250+ by not replacing the fan switch (heater control module) on my daughter's 2012 Ford Escape that I bought for her on Friday. The previous owner told me that the 2 lower speeds didn't work & that his mechanic told him that the switch needed to be replaced. I put what I learned from SD Premium to good use & found that the switch worked just fine & it needed a $18 blower motor resistor. Now I just need to diagnose the lift-gate ajar light that won't go out. 👍
Like that you are teaching the basics about how refrigerant works. Most people leave that out. Very good that you get great questions from your son, he adds a lot to your videos. A lot of the same questions the viewers will have.
I remember doing hundreds AC system fitments and hundreds of R12 to R134a retrofits on brand new vehicles from Hyundai in the 90s when I started my apprenticeship, it was gravy work, my workmates and I figured out quicker ways of doing the job because of repetition, we also learned the basics operation of AC systems and all the components. Made big money from "time saved" bonuses and also got a head start on diagnosing because we knew what normal system operation should look like through repetition. Top work on the safety aspects in the video, Paul.
Ha ha, I was thinking exactly the same thing, it is an elegant and completely safe test for a bad engine ground. To put external power to the housing to test the final pathway to ground is always more spooky.
For people like myself,not only do we get an excellent presentation of the complex ins and outs of how the AC systems functions .we keep increasing our knowledge of the English language your pronunciation of every word it's so clean.thank you..and your team God bless.
Thank you for this video. My wife cousin have a mazda 3 with the AC that just not working. I can help her now. Here in the south AC is a must. Thanks again.
And I'm very fortunate to have my son working for me 😃 watch some of my new videos and see how good he has gotten at editing. Game changer type stuff imo Thank you!
A special thanks, to cameraman Caleb, for putting up with a parent, when goofing off and friends are the things of choice!! Lol We feel for ya, brother!!
I'm glad I found this video. The first AC I worked on was badly wired to a toggle switch. Burned a lot of connectors and wires through the harness. Somehow even burned out the cooling fan relay and connectors. I traced any issue the ac system could have mechanically, then started on electric. Those harness are very hard to work through, they attach to everything. The greatest part of this job is its for work and the parts changer there won't admit wiring a compressor directly to stay on is a big mistake. Anyway I'm going on day 6 of rebuilding the ac and cooling fan systems. For the first ac I've seen everything on, this is an awesome learning experience as well as a huge challenge. Videos like this are lifesavers. And you make me look like I learned ac systems overnight. Thank you for this 2015 sierra 1500. And no, it's not the condenser lol 15:05
the chanell has opened up a whole new world for me. i am 64 years old have always went with gut not anymore now i can diag and prove findings. it is so nice to be able to diag a problem and not hope i have it correct. the feeling of knowing i am not guessing is wonderful and i have only had the premium for about a month if you are on the fence get on the correct side it will be the best money you have ever spent. thanks for telling me scanner danner that you would help me wish i had knows a long time ago the value.
Nice electrical testing! When I heard "flood car" I thought of the Katrina cars. Make sure to wear protective personal equipment when working around flood cars! Don't gets cuts! If so seek immediate medical attention! Think SEPSIS! Nice Job Paul!
Best thing I have invested in is the ScannerDanner field guide and premium channel ! My knowledge of electrical design and circuit testing is better than ever before . I no longer have to guess if a sensor is bad or something else that would require changing parts that’s not needed . Thanks Paul for taking time to teach.
Paul the top light is to tell you which post on the top is the power side of the load circuit. You take the switch and go to LED and if it's green or Red it tells you which top post is the power side of the load side which you accomplished with the test light which was the red terminal. Tells which post is 30 or 87 and If you'd have toggled the switch to LED it would have been glowing red. The LED will shine only when power & ground is present and the switch is in the LED position. Lets you do voltage drop testing & know what top terminal is 30 or 87 with just the flip of the switch. I printed the manual from the CD & have the manual shrunk down to fit in the box for when I have/had questions b/c I used to think the same about the load side light but it only lights in the LED position if there is voltage and a ground. Hope this helped Paul.
@@ScannerDanner Yea I see all your videos on both channels and one you ask stuff you answered yourself on older videos so that explains it. Thought maybe the heat was getting to you 🤣😂
I just got this tool and am still a little confused about its operation. I am not a newbie to this stuff either. You mentioned thier was a manual or a DVD with the tool? I did not get either with mine. I'm gonna call ASE Wave and see what they say. I need to take it out to a known goof car and play around with it also. Be very careful about the current draw in the circuit you are testing. The switch is only rated for 15 amps. Great video.
I love this guy. Not only does he give detailed step by step guided help on how to diagnose and repair the issue....but he explains how it works, and why its broken now in terms even a woman can understand. I love diagnosing and fixing my car myself when i can physically but im the type where i need to know how it works before i go taking it apart to fix it. Love this guy
Thank you so much! You will like the content on this channel then. I'm an instructor at a technical college for the past 19 years :-) but I also know that I am not for everyone. The people that don't like my videos are the ones just searching for an answer to fix their car. They don't care about learning how to troubleshoot. I don't just catch the fish and feed it to you, I teach you how to fish for yourself. Thanks for seeing that. God bless you
@@ScannerDanner that's why I enjoy your videos so much because I am trying to learn how to troubleshoot and diagnose MY OWN VEHICLE MYSELF. I'm very independent so whenever I started troubleshooting and diagnosing my vehicle myself . I would go to my favorite auto parts store and ask for a certain part, or tell my mechanic....hey i need this done.... almost every time the reply would be a how do you know who told you that. And almost act offended. so I stopped going and I started going to my local auto salvage and taking the parts off myself and putting them back on my car because if you take off the part usually figure out how to put it back on. at first I thought I was going to hate it but loved it cuz I felt like after I diagnosed and fixed my own car i started to enjoy my car more and even was proud of myself. but then I just didn't want to just fix my car I wanted to know how it works and why it works that way that way while I was troubleshooting and came across something that was not your obvious problem i could think outside the box and figure it out. I recently replaced my head gasket....had help......but i have a great mechanic friend who lets me do almost e everything and only steps in if im doing something wrong.
It’s important to know how something works when taking it to a mechanic to do the work, this helps you avoid being charged for something you don’t need or even worse something that they never did. Knowledge is always of value.
I used to have the same problem with suzuki escudo running through a flood. Just had a broken fuse. Clean the ac pulley and replaced the fuse was all I did. Guess I got lucky. Thanks for the lesson Paul n Caleb. 😍
You will start seeing some merch listed under all of my UA-cam videos in the next few days. In the mean time here is the link to my store teespring.com/stores/scannerdanner-2 I will be donating 100% of the proceeds from ALL of my merch sales to organizations that help people! Not all of them will be faith based but a majority of them will be I am sure. I don't have the list complete yet but you will see it on my website when I do. I will also keep the number of sales public so you all can hold me accountable. Thank you all so much!
ScannerDanner I got a 2005 odyssey I put a new ac clutch because the clutch went out it works good for now but when I turn the ac off the clutch Pulley it keep turning very very slowly what you think it could be any tips thank you
ScannerDanner I love AESwave, just wish they would finance to DIY’rs. You should tell them of all the sales they are missing out on. Keep up the good work! Love the vids
I'm not a premium member, currently. However, I did do the UA-cam premium just before the switch. I watched the class lectures, countless case studies and gained the understanding of how car electrical systems work. Since then, I quickly passed my lead tech in skill and productivity. Engine Performance and Electrical ASE tests were a breeze. I've been moved to the busiest shop in my company. My new lead tech is very impressed with my skills and will ask for my input. Lastly, I've triple my pay in 3 years. Paul, I'm 41 years old, was laid off 4 years ago, my kids are grown, so I decided to do what I like doing, fix cars. I started as an oil and tire changer for minimum wage. Today, I'm a Senior Tech and well paid. You have given me the knowledge to make me successful. I thank you from the bottom of my heart. When I finish paying off my Matco jacket (came with a free tool box) I'll be back on premium.
Thank you Caleb for assisting your dad!! I understand the properties of R134 much better now; thanks Paul for explaining, as well as the case ground check- never thought of it that way!!!
Scanner Danner premium is without a doubt a life changing career advancement. I got my L1 as a result of the premium side of this channel. I invest thousands of dollars in my tool and education is my best tools. I'm still a member because it keeps my edge Sharp.
And.. I was a Scanner Danner premium subscriber for a year...I've got the book, I use it often. Danner has a great electrical diagnosis routine..he has it figured out. I'm with him as far as using an staying away from an ohm meter.Voltage and amperage checks are key. Just wish i could have him give me a class on the days I get stumped.
@3:37 me personally, I started taking that pressure/temperature relationship thing with R134a with a grain of salt after I had a Chevy Silverado once that had 100 psi reading on the gauges with the engine off, and it was around 100 degrees when I took the pressure reading. I decided to hook up the machine and recover the system anyway. It wound up being a good thing I did because despite having all that pressure, it only recovered 0.1 lbs of Freon/refrigerant. Could’ve wasted SO much time if I hadn’t done that first. Kudos on bringing that up.
@Morley what SD says is correct as long as the refrigerant is in a saturated condition (liquid & gas present). In your case it's very likely that you had only gas in the system and possibly some air too.
Yet another useful video by Paul, and SDP is way worth the 11 bucks or so, the training he gives you is unparalleled. he shows the complete process, even his missteps. he explains everything as he goes, and when he gets off topic its actually always helpful, I figure he saved me hundreds, if mot thousands of dollars by his teaching through SDP and Utube. I even repaired my Home HVAC because of his teaching on thermistor operation. Ive been wrenching for 35 years and Paul gives the best Diagnostic training I have ever seen, get SDP!
I have no doubt that the premium channel is well worth the price, you will see me there as soon as I finish my shop. Thanks for the great video, and wear whatever color shirt you are comfortable wearing, we all know it's too hot to be wearing dark colors.
thanks again always i learn from you my age 62 bu mechanic line job whatever you call it i lovett i am a mechanic since 1977 up to now i do all kind car transmissions engines A/c work but sure in difficulties between old car & new technology of course you are A master thousands benefit from your fruitful lecture i learned A lot you are one of the best of my followers again i say thanks a lot lasting health and wellness i relay, appreciate for you sincere efforts to benefit others
CH2FCF3 (r134a gas) has boiling point of −26.3 °C (−15.34 °F) at atmosferic pressure(1bar/100Kpa) This is a great video buddy,keep up the good work and i appreciate you sharing the knowledge
You are a true mechanic, very knowledgeable. I just change parts until I fix the problem 😂 I need to learn how to do diagnostic. The best part I liked most about the video is that you were teaching your son as you were teaching us. Tell your son he is lucky to have a dad that takes the time to teach him, and you are lucky to have a son that wants to learn. A subscriber now, keep at it! 🤙🏽🤙🏽🤙🏽
my dodge durango 2004 AC stopped working and when the fans kick on i hear a loud tapping in the panel passenger side back by the 3rd row. When i bought the car i heard the rear AC didnt work but the front did. When i got it nothing worked. Also when i pull the cap off the low pressure valve it almost spits out tiny bits of liquid. You're a really good teacher btw. Your son is a lucky young man.
Exceptional video! By the Way You are a great dad! This is the same thing I do with my kids when I'm working on their cars so they learn as we go. I also encourage them to pass on their knowledge to their kids. it is priceless. TY
I been a member for long time now and i love it. The content is great and super handy i been a mechanic for 25 years and i am always learning still and he has definitely made me faster at diagnosing lots of situations that ya i would have figured out but made it faster by doing his way ..thanks again SD for all the great content .cheers Markus
Trying to troubleshoot my AC and this is the best video I’ve come across! You’re a natural teacher and are going to help so many people with your content. Thank you! 🙂
I'm a SD premium member and I don't like this kind of advertising but to show my appreciation and support for work that Paul is doing I'm gonna make an exception. I've been watching his welfare channel and didn't get a thing what he was teaching. And now slowly I'm getting how the system works and can do my own diagnosis and repairs way better than so called pseudo parts changing mechanics.
Although I'm no longer a technician, I still enjoy watching your videos. I still learn and I will continue to learn and your channel helps. Thanks for doing what your doing.
I appreciate the well explained, articulate, helpful beyond words lessons, tips and proceedures you had for your kiddo. :) the fact that we all have this video accessible too is just a major bonus. and a brilliant example of being a dad. subscribing now.
The way you explain things is awesome. You remind me of my dad when he was teaching me about cars. Caleb is one lucky kid!! I will definitely be subscribing and watching more of your videos. Thanks for the knowledge and keep up the good work man you are great.👌
Thank you for having your son work the camera. The last video I watched, the guy wore the camera on his head and moved around so much I was dizzy by the end. I forgot most of what he said before I could stand up and work on my car. 😁
I'm an electrical engineer by education and I am very impressed with your videos. You have excellent troubleshooting skills and always come back to basic circuit analysis which is the key to locating the source of electrical problems with certainty.
Great job guys - thorough, not hit-and-miss, one of the best videos on ac! So many killed underneath vehicles - always use chocks when jacking vehicle.
You really help connect the dots Paul for us who understand theory and concepts and relate in laymen terms . Thank you for your sharing of knowledge and am purchasing the book and SD Premium very soon.
I put the e brake on once to change a U joint on an F 150. When the drive shaft came down that truck started moving. I flew out from under it a hundred mph on a creeper. I was lucky the air hose was on the right side of the creeper and didnt stop me. The truck rolled all the way out the shop and into a lake. That e brake was a disk brake at the back of the transfer case that required a drive shaft to be in place to work.
Love the vids Danner as I am an electronics/electrical tech and also power engineer. Love troubleshooting. I've had relays click also thinking one was good only to find it was still bad! Load side contact was screwed! New relay and my trouble was clear! Love the safety on jacking up the car. Too many people killed by not thinking! Cheers from Ontario, Canada!
I said it before and I’ll say it again. Thank you for taking the time to push safety with jack stands and using the e brake to hold the car. Also keeping legs/feet out from under the rotor. I see it way to many times.
@@ScannerDanner I am 66 years old. I use to turn wrench for a living a long time ago. A lot of things have change, but even then i had to use coming sence and loget. and those I feel are the best tools some time and this video made me look at my problem with those in mind. again great video,
6 minutes in - Damn, he done drunk the Freon. Serious now - this is excellent , real time , tuition on the principle of refrigeration. It's about 9 pm on a Saturday night here in the UK , the AC on my Ford does not work and I'm on U tube to escape the enthralling (not) Saturday night TV. I've watched about the first ten minutes of this production and will come back for the remainder tomorrow.
like how you find different ways to explain the same thing. people learn in different ways .great video i have 9.48 v to my ac clutch but 14.3 at the box

You are so what I need in my life. I have asked for a teacher that could explain things where I could understand what is going on. I just got my compressor changed in my car. And as soon as I did my water pump started to go bad. Then my car would not start, so I had to get a new battery. Then the battery light would not go off and I was told I need a new alternator. It has been a domino effect with the issues in my car and the mechanic I have can not explain anything except that the part is bad. I don't mind paying money as long as I can learn something in the process.
I know that everything I attract is a lesson for me to learn. Now I have attracted you, a teacher that can help me understand these attractions so I can better my situations in life. I love the way you explain using visuals and in multiple scenarios . Your teaching skill is that of a master. I plan to join the Scannerdanner Premium classes so I can get more of your teachings. I can see you wholeheartedly love what you do and I appreciate you for that.
Great job and explanation. The pressure/temperature relationship was good as pv/t = pv/t (Charles and Boyles law works) and I especially liked the use of the relay tester as well as continuity checks. Your vocation is not in auto mechanics but rather should be in teaching practical sciences or a vocational technical school, but the pay is poor. I use the emergency brake in addition to chocks and leave the wedding band off while working. You enlightened me and I appreciate the effort.
Scanner Danner premium changed my life and the way I diagnose... Highly recommend this to anyone that has a passion for the trade and would like to better your knowledge.
Thank you Ruaan!
I like how you find different ways to explain the same thing. people learn in different ways .great video
Hands down the "BEST" instruction video I have ever seen. Easily understood. Fantastic job. I will look forward to more. Great job Bro.
Thank you!
Very nice example!! Even Caleb is picking up the material!! This is so difficult to understand, and how it all works!! When I was a teen, a A/C tech neighbor had retired, but was still doing service calls, and used me as a helper. He tried to teach a young teen, some basic info, and he couldn't break thru!! I just couldn't understand it, and wouldn't listen! I went a different way!
The hardest part for me, was understanding the idea that refrigerant boiled at -40 degrees!! I knew that water boils at 212 deg, so how could refrigerant be hot enough to cook pasta at -40, and how did that make me feel cold!! My weak brain couldn't get he idea! It just held me back for so long! It wasn't until I learned the basic principles of science, how it all worked! For me, it was the realization of what "BOILS" means!!
Basic science! Boils means CHANGE FROM A LIQUID STATE TO A VAPOR STATE!! It doesn't mean that it will make pasta for us!! And when it changes,(BOILS) it absorbs heat!! So, the point that refrigerant boils, it absorbs the surrounding heat, and makes things around it feel cool (or scientifically, the absence of heat)!
The rest I could fit together, and it all made sense to me!! The A/C system is just a controlled compression and then release of a material that helps absorb the excess heat, to make us feel good!!
Great job, Scan!! And Caleb too! Thanks for sharing!! AND TEACHING!! AND ENTERTAINING!!
Yeah, and when the refrigerant level gets so low you hear the expansion device hiss behind the dash almost like a gas stove would, you don't get cold air anymore because liquid->vapor transition isn't happening anymore.
Every Mechanic should watch this guy
I love when they do a proper tutorial just like they're teaching I appreciate that as many of us do !
God bless you guys. I've done so many jobs on my car with succession and it'll be the first time I tackle AC problems. Cheers!
Excellent info! I loved the pressure readings explanation with regard to air temps.
The $11 that I pay for SD Premium is well worth it. This past Saturday I saved a good $250+ by not replacing the fan switch (heater control module) on my daughter's 2012 Ford Escape that I bought for her on Friday. The previous owner told me that the 2 lower speeds didn't work & that his mechanic told him that the switch needed to be replaced. I put what I learned from SD Premium to good use & found that the switch worked just fine & it needed a $18 blower motor resistor. Now I just need to diagnose the lift-gate ajar light that won't go out. 👍
There would be a switch for that one too my friend
Like that you are teaching the basics about how refrigerant works. Most people leave that out. Very good that you get great questions from your son, he adds a lot to your videos. A lot of the same questions the viewers will have.
Paul,
Great diagnosis, explanation, and video. Thank you to you and Caleb!
God bless
Paul (in MA)
First time here, going to see all your videos if they are like this. No joke, your teaching is spot on for me to understand clearly. thank you
They are all this way. Thank you! I've been teaching at a technical college for 20 years 😉
Happy to have you here on my channel!
I will NEVER wear a light gray shirt again when it is 95 degrees. I am so sorry. I have held onto this video for a year because of this lol.
Ah, come on. Everyone sweats, especially in such a heat. I guess everyone watching your videos couldn't care less. :-)
Navy blue works for me
ScannerDanner I don’t think most people who work on stuff when it’s hot out care that your shirt is wet from a little sweat.
Imagine doing this in Texas man lol 😂
bigmac82 I live in Texas so I know exactly what you are talking about, it can be pretty miserable.
I remember doing hundreds AC system fitments and hundreds of R12 to R134a retrofits on brand new vehicles from Hyundai in the 90s when I started my apprenticeship, it was gravy work, my workmates and I figured out quicker ways of doing the job because of repetition, we also learned the basics operation of AC systems and all the components.
Made big money from "time saved" bonuses and also got a head start on diagnosing because we knew what normal system operation should look like through repetition.
Top work on the safety aspects in the video, Paul.
Most excellent! I appreciate the lessons large and small. Especially the diagram and ground testing of the housing and the explanation of the circuit.
Ha ha, I was thinking exactly the same thing, it is an elegant and completely safe test for a bad engine ground. To put external power to the housing to test the final pathway to ground is always more spooky.
For people like myself,not only do we get an excellent presentation of the complex ins and outs of how the AC systems functions .we keep increasing our knowledge of the English language your pronunciation of every word it's so clean.thank you..and your team God bless.
Funny how I comment before watching the video 🤣 much appreciated ScannerDanner. This is Neo from South Africa.
Thank you for this video. My wife cousin have a mazda 3 with the AC that just not working. I can help her now. Here in the south AC is a must. Thanks again.
finally a man with sense , work under a sun shade
Mr daneer you're great man nice job sir
What a treasure trove of information, Scanner Danner is... Caleb is very fortunate to have a Dad like that... 🤷🏼♂️✊🏽
And I'm very fortunate to have my son working for me 😃 watch some of my new videos and see how good he has gotten at editing. Game changer type stuff imo
Thank you!
A special thanks, to cameraman Caleb, for putting up with a parent, when goofing off and friends are the things of choice!! Lol
We feel for ya, brother!!
I'm glad I found this video. The first AC I worked on was badly wired to a toggle switch. Burned a lot of connectors and wires through the harness. Somehow even burned out the cooling fan relay and connectors. I traced any issue the ac system could have mechanically, then started on electric. Those harness are very hard to work through, they attach to everything. The greatest part of this job is its for work and the parts changer there won't admit wiring a compressor directly to stay on is a big mistake.
Anyway I'm going on day 6 of rebuilding the ac and cooling fan systems. For the first ac I've seen everything on, this is an awesome learning experience as well as a huge challenge. Videos like this are lifesavers. And you make me look like I learned ac systems overnight. Thank you for this
2015 sierra 1500. And no, it's not the condenser lol 15:05
Good video Paul and Caleb. Go cool off guys. 👍👍👍
the chanell has opened up a whole new world for me. i am 64 years old have always went with gut not anymore now i can diag and prove findings. it is so nice to be able to diag a problem and not hope i have it correct. the feeling of knowing i am not guessing is wonderful and i have only had the premium for about a month if you are on the fence get on the correct side it will be the best money you have ever spent. thanks for telling me scanner danner that you would help me wish i had knows a long time ago the value.
Thanks so much!
Nice electrical testing! When I heard "flood car" I thought of the Katrina cars. Make sure to wear protective personal equipment when working around flood cars!
Don't gets cuts! If so seek immediate medical attention!
Think SEPSIS! Nice Job Paul!
how nice
Just love when I can use a refresher in some car system, and I can just watch a ScannerDanner video to get right back up to speed! Brilliant!
Thank you Jeremy!
Gracias Paul eres un gran maestro yo tengo tu libro y estoy suscrito me as ayudado mucho es pero q sigas muchos años más muchas gracias y saludos
Best thing I have invested in is the ScannerDanner field guide and premium channel ! My knowledge of electrical design and circuit testing is better than ever before . I no longer have to guess if a sensor is bad or something else that would require changing parts that’s not needed . Thanks Paul for taking time to teach.
Paul the top light is to tell you which post on the top is the power side of the load circuit. You take the switch and go to LED and if it's green or Red it tells you which top post is the power side of the load side which you accomplished with the test light which was the red terminal. Tells which post is 30 or 87 and If you'd have toggled the switch to LED it would have been glowing red. The LED will shine only when power & ground is present and the switch is in the LED position. Lets you do voltage drop testing & know what top terminal is 30 or 87 with just the flip of the switch. I printed the manual from the CD & have the manual shrunk down to fit in the box for when I have/had questions b/c I used to think the same about the load side light but it only lights in the LED position if there is voltage and a ground. Hope this helped Paul.
I know, smh, this is the problem with releasing a video that is a year old. I have since figured out how to use the tool properly lol
@@ScannerDanner Yea I see all your videos on both channels and one you ask stuff you answered yourself on older videos so that explains it. Thought maybe the heat was getting to you 🤣😂
Haha nice!
I just got this tool and am still a little confused about its operation.
I am not a newbie to this stuff either. You mentioned thier was a manual or a DVD with the tool?
I did not get either with mine.
I'm gonna call ASE Wave and see what they say.
I need to take it out to a known goof car and play around with it also.
Be very careful about the current draw in the circuit you are testing.
The switch is only rated for 15 amps.
Great video.
@@tpcoachfix It has a 15A resettable CB at the bottom.
I love this guy. Not only does he give detailed step by step guided help on how to diagnose and repair the issue....but he explains how it works, and why its broken now in terms even a woman can understand. I love diagnosing and fixing my car myself when i can physically but im the type where i need to know how it works before i go taking it apart to fix it. Love this guy
Thank you so much! You will like the content on this channel then. I'm an instructor at a technical college for the past 19 years :-) but I also know that I am not for everyone. The people that don't like my videos are the ones just searching for an answer to fix their car. They don't care about learning how to troubleshoot. I don't just catch the fish and feed it to you, I teach you how to fish for yourself. Thanks for seeing that. God bless you
@@ScannerDanner that's why I enjoy your videos so much because I am trying to learn how to troubleshoot and diagnose MY OWN VEHICLE MYSELF. I'm very independent so whenever I started troubleshooting and diagnosing my vehicle myself . I would go to my favorite auto parts store and ask for a certain part, or tell my mechanic....hey i need this done.... almost every time the reply would be a how do you know who told you that. And almost act offended. so I stopped going and I started going to my local auto salvage and taking the parts off myself and putting them back on my car because if you take off the part usually figure out how to put it back on. at first I thought I was going to hate it but loved it cuz I felt like after I diagnosed and fixed my own car i started to enjoy my car more and even was proud of myself. but then I just didn't want to just fix my car I wanted to know how it works and why it works that way that way while I was troubleshooting and came across something that was not your obvious problem i could think outside the box and figure it out. I recently replaced my head gasket....had help......but i have a great mechanic friend who lets me do almost e everything and only steps in if im doing something wrong.
@@elizabethramos3058 heck yeah, this is awesome! I've always loved seeing my female students who show all the guys what's up. Keep up the great work!
It’s important to know how something works when taking it to a mechanic to do the work, this helps you avoid being charged for something you don’t need or even worse something that they never did. Knowledge is always of value.
you learn what he teaches at technical college at a fraction of the cost its well worth the 11 dallars a month
that's 37 cents a day what Danner teaches you its priceless.
Sounds great, where do I sign up?
I used to have the same problem with suzuki escudo running through a flood. Just had a broken fuse. Clean the ac pulley and replaced the fuse was all I did. Guess I got lucky. Thanks for the lesson Paul n Caleb. 😍
I highly recommend not to drink refrigerant anymore🤣🤣
Next video, how to drink refrigerant from a bottle
😂😂
Keyword - Anymore
or any less ? LoL
He's so carefree!
Theres A lot he doesn't care about lolllll
Well we’ll fourth the money!! The content he provides for the price hands down unbeatable value. You never stop learning and you never stop training.
You will start seeing some merch listed under all of my UA-cam videos in the next few days. In the mean time here is the link to my store teespring.com/stores/scannerdanner-2
I will be donating 100% of the proceeds from ALL of my merch sales to organizations that help people! Not all of them will be faith based but a majority of them will be I am sure. I don't have the list complete yet but you will see it on my website when I do. I will also keep the number of sales public so you all can hold me accountable. Thank you all so much!
ScannerDanner I got a 2005 odyssey I put a new ac clutch because the clutch went out it works good for now but when I turn the ac off the clutch Pulley it keep turning very very slowly what you think it could be any tips thank you
@@olvincontreras9103 you need to increase your air gap, it is rubbing
ScannerDanner I love AESwave, just wish they would finance to DIY’rs. You should tell them of all the sales they are missing out on. Keep up the good work! Love the vids
ScannerDanner thanks I took it to the shop today and they told me that the compressor was going out so I was about to buy a new compressor
@@olvincontreras9103 wow the shop was ready to screw you over.
ScannerDanner channel is the best investment !!
ScannerDanner Premium is an awesome way to learn troubleshooting fundamentals! Totally worth it!
agree
I'm not a premium member, currently. However, I did do the UA-cam premium just before the switch. I watched the class lectures, countless case studies and gained the understanding of how car electrical systems work. Since then, I quickly passed my lead tech in skill and productivity. Engine Performance and Electrical ASE tests were a breeze. I've been moved to the busiest shop in my company. My new lead tech is very impressed with my skills and will ask for my input. Lastly, I've triple my pay in 3 years.
Paul, I'm 41 years old, was laid off 4 years ago, my kids are grown, so I decided to do what I like doing, fix cars. I started as an oil and tire changer for minimum wage. Today, I'm a Senior Tech and well paid. You have given me the knowledge to make me successful. I thank you from the bottom of my heart.
When I finish paying off my Matco jacket (came with a free tool box) I'll be back on premium.
It is these kind of stories that mean more to me than any monetary gains. Thank you!
Thank you Caleb for assisting your dad!! I understand the properties of R134 much better now; thanks Paul for explaining, as well as the case ground check- never thought of it that way!!!
Man I just found you on here top shelf for a guy trying to get the ase test passed I'm gonna subscribe thank you
Scanner Danner premium is without a doubt a life changing career advancement. I got my L1 as a result of the premium side of this channel. I invest thousands of dollars in my tool and education is my best tools. I'm still a member because it keeps my edge Sharp.
Thank you so much for your continued support. I can't thank guys like you enough
It is very kind of you sharing your knowledge in the way you do since from my experience not a lot of people will do that. Thank you so much.
And.. I was a Scanner Danner premium subscriber for a year...I've got the book, I use it often. Danner has a great electrical diagnosis routine..he has it figured out. I'm with him as far as using an staying away from an ohm meter.Voltage and amperage checks are key. Just wish i could have him give me a class on the days I get stumped.
@3:37 me personally, I started taking that pressure/temperature relationship thing with R134a with a grain of salt after I had a Chevy Silverado once that had 100 psi reading on the gauges with the engine off, and it was around 100 degrees when I took the pressure reading. I decided to hook up the machine and recover the system anyway. It wound up being a good thing I did because despite having all that pressure, it only recovered 0.1 lbs of Freon/refrigerant. Could’ve wasted SO much time if I hadn’t done that first. Kudos on bringing that up.
@Morley what SD says is correct as long as the refrigerant is in a saturated condition (liquid & gas present). In your case it's very likely that you had only gas in the system and possibly some air too.
Fantastic wonderful classes in premium channel. All electric fundimental you need to diagnose step by step.
I have several subscriptions but SD Premium is the best value without a doubt.
Yet another useful video by Paul, and SDP is way worth the 11 bucks or so, the training he gives you is unparalleled. he shows the complete process, even his missteps. he explains everything as he goes, and when he gets off topic its actually always helpful, I figure he saved me hundreds, if mot thousands of dollars by his teaching through SDP and Utube. I even repaired my Home HVAC because of his teaching on thermistor operation. Ive been wrenching for 35 years and Paul gives the best Diagnostic training I have ever seen, get SDP!
Awesome! My "off topic" discussions are truly within the topic, it is just a lot to absorb the first time through :-)
What I could have been with a father like that. Great teaching as well - hands on, verbal, and visual.
I have no doubt that the premium channel is well worth the price, you will see me there as soon as I finish my shop. Thanks for the great video, and wear whatever color shirt you are comfortable wearing, we all know it's too hot to be wearing dark colors.
thanks again always i learn from you my age 62 bu mechanic line job whatever you call it i lovett i am a mechanic since 1977 up to now i do all kind car transmissions engines A/c work but sure in difficulties between old car & new technology of course you are A master thousands benefit from your fruitful lecture i learned A lot you are one of the best of my followers again i say thanks a lot lasting health and wellness i relay, appreciate for you sincere efforts to benefit others
Your analogy with the water bottle was spot on. CALLED SATURATED PRESSURE LIQUID AND VAPOR
thank you! So many people do not understand what "rest pressure" actually is telling you and what it is not
great class your son should be proud of you because you are teaching him how is done
CH2FCF3 (r134a gas) has boiling point of −26.3 °C (−15.34 °F) at atmosferic pressure(1bar/100Kpa)
This is a great video buddy,keep up the good work and i appreciate you sharing the knowledge
Thanks for the info and the comment!
4 = 4 Fl atoms, 3 = # of Hydrogen atoms plus 1, 1 = # of Carbon atoms minus 1. Hence 134a = 2 carbons, 2 Hydrogen atoms and 4 Fl atoms.
You are a true mechanic, very knowledgeable. I just change parts until I fix the problem 😂 I need to learn how to do diagnostic. The best part I liked most about the video is that you were teaching your son as you were teaching us. Tell your son he is lucky to have a dad that takes the time to teach him, and you are lucky to have a son that wants to learn. A subscriber now, keep at it! 🤙🏽🤙🏽🤙🏽
thank you for the feedback my friend, really appreciate it
my dodge durango 2004 AC stopped working and when the fans kick on i hear a loud tapping in the panel passenger side back by the 3rd row. When i bought the car i heard the rear AC didnt work but the front did. When i got it nothing worked. Also when i pull the cap off the low pressure valve it almost spits out tiny bits of liquid.
You're a really good teacher btw. Your son is a lucky young man.
Exceptional video! By the Way You are a great dad! This is the same thing I do with my kids when I'm working on their cars so they learn as we go. I also encourage them to pass on their knowledge to their kids. it is priceless. TY
I been a member for long time now and i love it. The content is great and super handy i been a mechanic for 25 years and i am always learning still and he has definitely made me faster at diagnosing lots of situations that ya i would have figured out but made it faster by doing his way ..thanks again SD for all the great content .cheers Markus
Thank you Markus!
Trying to troubleshoot my AC and this is the best video I’ve come across! You’re a natural teacher and are going to help so many people with your content. Thank you! 🙂
Thank you!
Scanner danner premium is the best training you can do for the money anywhere and anytime
Thank you so much!
Your son should be very proud of you brotha. I can relate with what you are doing and why. I do the same with my son. New subscriber here.
I'm a SD premium member and I don't like this kind of advertising but to show my appreciation and support for work that Paul is doing I'm gonna make an exception. I've been watching his welfare channel and didn't get a thing what he was teaching. And now slowly I'm getting how the system works and can do my own diagnosis and repairs way better than so called pseudo parts changing mechanics.
Hahaha "welfare channel" thanks my friend
Best on Utube. Thank you sir! Thank you for teaching your son. My son is 16 and we are working on his AC in his 2002 Silverado 4x4. Thank you.
Although I'm no longer a technician, I still enjoy watching your videos. I still learn and I will continue to learn and your channel helps. Thanks for doing what your doing.
I appreciate the well explained, articulate, helpful beyond words lessons, tips and proceedures you had for your kiddo. :) the fact that we all have this video accessible too is just a major bonus. and a brilliant example of being a dad. subscribing now.
Thanks my friend
The way you explain things is awesome. You remind me of my dad when he was teaching me about cars. Caleb is one lucky kid!! I will definitely be subscribing and watching more of your videos. Thanks for the knowledge and keep up the good work man you are great.👌
Thank you and welcome!
Thank you for having your son work the camera. The last video I watched, the guy wore the camera on his head and moved around so much I was dizzy by the end. I forgot most of what he said before I could stand up and work on my car. 😁
I'm an electrical engineer by education and I am very impressed with your videos. You have excellent troubleshooting skills and always come back to basic circuit analysis which is the key to locating the source of electrical problems with certainty.
Thank you very much! Mean a lot coming from someone like you
Great job guys - thorough, not hit-and-miss, one of the best videos on ac! So many killed underneath vehicles - always use chocks when jacking vehicle.
Man, I learned vehicle AC operation so much from watching many of your AC repair videos. Finally subbed. 👍
Awesome, thank you!
Can’t always rely on the scanner-
But you have to rely on the Danner!
Great information- insight and troubleshooting ideas-
Means the world to me and you learn so much on it, it's well worth the money
Haven't quite finished watching the video yet, but I wanted to thank you for demystifying AC functionality for me. 👍
You really help connect the dots Paul for us who understand theory and concepts and relate in laymen terms . Thank you for your sharing of knowledge and am purchasing the book and SD Premium very soon.
Look forward to hearing more from you, thank you!
Join the premimum. The classroom material is excellent. He can make anything interesting, even things you already know.
Thank you Andrew!
What a great explanation. I love it. Learned from this video how to diagnose 'clutch does not engage' issue. Thank you very much.
I put the e brake on once to change a U joint on an F 150. When the drive shaft came down that truck started moving. I flew out from under it a hundred mph on a creeper. I was lucky the air hose was on the right side of the creeper and didnt stop me.
The truck rolled all the way out the shop and into a lake.
That e brake was a disk brake at the back of the transfer case that required a drive shaft to be in place to work.
Love the vids Danner as I am an electronics/electrical tech and also power engineer. Love troubleshooting. I've had relays click also thinking one was good only to find it was still bad! Load side contact was screwed! New relay and my trouble was clear! Love the safety on jacking up the car. Too many people killed by not thinking! Cheers from Ontario, Canada!
I said it before and I’ll say it again. Thank you for taking the time to push safety with jack stands and using the e brake to hold the car. Also keeping legs/feet out from under the rotor. I see it way to many times.
Excellent of your sequence of explaining with appropriate video with detailing
Scanner dinner could actually change your life as a did to me .. Thank you Paul thank you for everything.. And Special hi to Caleb
Thank you my friend
this is about the best video i have seen yet on a/c problem
funny, I've heard the complete opposite on this video too. To those who know right? Thanks so much
@@ScannerDanner I am 66 years old. I use to turn wrench for a living a long time ago. A lot of things have change, but even then i had to use coming sence and loget. and those I feel are the best tools some time and this video made me look at my problem with those in mind. again great video,
Love watching you, and I've learned so much from you. Keep up the good work and may God bless you and your family
Excelente video!!. Este video debería estar en Premium tambien. Gracias
6 minutes in - Damn, he done drunk the Freon.
Serious now - this is excellent , real time , tuition on the principle of refrigeration.
It's about 9 pm on a Saturday night here in the UK , the AC on my Ford does not work and I'm on U tube to escape the enthralling (not) Saturday night TV. I've watched about the first ten minutes of this production and will come back for the remainder tomorrow.
Great explanation of the system! Will be putting that in my mental rolodex! Had an A/C issue before but spent $300 for a simple fix!
like how you find different ways to explain the same thing. people learn in different ways .great video i have 9.48 v to my ac clutch but 14.3 at the box
