DIY- Troubleshooting No Air Conditioning
Вставка
- Опубліковано 2 жов 2024
- Your favorite DIYer returns from prolonged absence to troubleshoot an air conditioning problem that would have caused Scotty's typical minions to dump $20 right into the ozone layer before they even got a clue.
This kind of detective work on a car is almost always fun, and it sure makes a helpful video. Nicely done.
Matt, just ignore the trolls and haters. By spending so much of -your- our time responding to trolls on followup videos, you're letting them plan the agenda for future recordings. Most of us don't need to hear it, and your videos will be faster, cleaner and better.
Folks like you are what make this country great. I love calling it home since early 80s. I thank You 👨🏻🔧
Great Video man! As a refrigeration mechanic i hear "Oh it just needs a little freon" on the daily lol. Most times its just a simple electrical issue
You are very knowledgeable but you seem to allow the stage you're on (the internet) dictate you're delivery. Don't worry about and please stop giving into negative comments and people in general. I learned a lot from whatching this video.I had to rewind a few parts due to your "typical hack" comments. My word to you is if you are sharing knowledge do so without the bitter shade throwing. In this world no one knows it all however, all of our knowledge together can move mountains. Thanks again for the informative vídeo.
Schroeder's Box don't let them get you down! God bless you for all of your efforts and I really appreciate you for posting your knowledge for people like me to see so that we can help ourselves in times of desperate need. I've been on my own since 13. I've been learning watching others mostly from you tube and Google (since my papa is gone now). Your knowledge is greatly appreciated and every little bit counts. Thank you!
Learning along from your approach procedure thank you very much
I was like a monkey hunting around for coconuts until I found this video! 😆 15:29 Thanks so much. You probably could use a couple drinks though! Lol
Using logic then brain contrary to your average mechanic love your video. I can’t believe how many thumbs down you got now we know exactly how many monkeys are out there. 👍
I could tell you’re really frustrated and have no patience with how much idiot repairs you see an air-conditioning on UA-cam it shows, me too !. Some of my videos about air-conditioning I talked to same way in frustration at the idiots and monkeys that you do.
Haha... cheers!!!😄😄
I gotta say... People are so freaking sensitive and they're getting free information, wtf, they should be happy for someone who is a professional giving them free information. They shouldn't be a mechanic or work in any shop, they'd be crying in a corner somewhere!
Nice to have you back Matt and at your very best too. Looking forward to the new video on your other paid channel. Top draw as always
I think your video would be much more effective by just telling us what and how you'd check and leave out all the sarcasm and criticisms of DIY'ers. We know we are amatures but like tinkering, saving money, and the feeling we've accomplished something.
Well half the people say to do it more, half say do it less... Since it's my channel I choose to go with the half that says do it more.
Hi I just discovered your videos and they seem very informative. In my opinion you should leave the negativity out and just own what you do. By making a point of everything that people might say and will say just eats away at what could be an informative and extremely confident approach. Let the haters hate and allow us to learn from your experiences.. cheers
Brilliant. Nothing better than a logical, sensible troubleshooting procedure. Well done.
Nice work. A little common sense and the power of observation goes a long way. Good logical approach to troubleshooting on most, if not all mechanical issues, appreciate you sharing the info.
Especially cars from the 90's (like mine) that are now 20+ years old. Resistors and relays have been baked for decades and fail....wiring gets brittle and fails.
Just found this video, and I absolutely love your approach to things. "Fix it with your brain instead of hunting around like a monkey looking for a coconut". I will be referencing this video as I hunt for my A/C issue. Thank you!
Im not kidding when I say this, my AC started blowing hot yesterday and my first thought was, damn I wish matt would put up a video. Thanks matt! Hope everything worked with the promotion
Simple to you and very hard for me. Thank you for explaining it for myself. Wonderful explanation!!!
Thank you so much for posting this video. I noticed last spring that my ac stopped working in my Nissan Xterra. I went a whole year thinking it was going to be an expensive fix. You helped me trouble shoot it. I first noticed the clutch was not coming on. I got my voltmeter and was about to try to chase down the issue, when i noticed that the AC compressor wasn't even plugged in. I plugged it in and BAM!! AC works perfect! I don't know if a mechanic just forgot to plug it in after doing other work on the engine, or if it was intentional. I hope it was not the latter.
I have also used the Devo Diagnostic Technique (DDT) as a problem solving guide for automotive issues. Nice success on the repair Matt
The DDT helped me to. Cranking, no start, so I proceeded to "crack that whip". It worked...lol.
Thanks for showing me your isolation technique. I actually had corrosion on that plug above the clutch. Fixed now.
I actually followed this technique in a similar fashion in my newly acquired 2001 Chevy trail blazer with the 4.3. You seemed to have almost the exact same vehicle or at least same looking engine. I have the exact same electrical issue. Previous owner told me it was low on pressure and needed to add some but I had to test all the connectors just to make myself content with that call. Unfortunately, I have three same issue as no power at all 0.00 volts going to the clutch. I had power at the low pressure switches. All my fixes and relays work properly. The pebbled now like he just confirmed for me is there's going to be a break somewhere and that's not going to be easy to find. I almost wish it was only a guide or relay.
Thankyou for this, fuse was bad but looked good. Swapped to a new fuse and click, on it came
Wow, I just discovered your channel. Finally someone who thinks like I do when performing automotive diagnostic procedures. Eager to watch more of your content.
Welcome aboard!
Thank you very much! We followed your testing procedures, and found a loose connector on the air conditioner clutch. Just as simple as it gets. But without your video and explanations, we were totally lost. Again, much thanks!!!!!
Thank your man again fantastic video I love them keep up the good work you’re funny you’re awesome you’re the man thank you👀🌿🙏I learn a lot from you from watching your videos fantastical Gracias
nice my ac not working watching ya video has got me motivated to fix mine as soon as i done my boll-joints thanks ya good inspiring thanks
Please answer this: So how did a wire get *cut* "while sitting at a stoplight"? Sounds and smells to me. I retired from the "repair" market years ago- for reasons of cheap, stupid people wanting free work- or trying to haggle my worth, or just plain lying to my face. I don't blame you one bit.
Because, as was mentioned twice in the video quite clearly and also shown on my other video, it was an improperly done butt connection from a previous repair.
I have seen this countless times- clean wire breaks like that at terms and connections. If you do this work with any regularity you will see this very often.
If you really were in the repair market you would have seen this as well countless times.
Schrodingers Box Yes- in 10 years I saw a few "repairs" that were done before they came into the Shop. Always fun- to hear the stories about who, what, and why. Bird's nests of bread twisters, paper masking tape, Duct tape, Scotch tape, bailing wire.
I did hear you mention it looked like a Butt connector might have been used, and had simply broken at the improperly deep cut strip- but there was no view of that broken piece, or of you repairing it in the video.
It seemed like you edited that part out.
I did not see the "other video" you speak of.
I really miss your stunning logic and methodical train of thought.
Nice to see you again.
HUBBABUBBA DOOPYDOOP Thanks man- sorry my answer maybe came off as brash but I misinterpreted your comment. There were several people who accused me of cutting the wire for sake of the video- as if I would do that on a customer's car (or need to do that). It pisses me off.
My apologies bro.
Forget about it. I got just as disgustipated as you about the whole mess- that's why I left, and started an entirely different career until I retired. Don't worry about what the kids here say- they're like flies on a turd.
I have a 2002 Mazda protégé. I'm now on a fixed income and have to do all work on my car myself. Thank God for UA-cam. My heater works but not the air-conditioner. The speed switch only works on 4 now, but I noticed that only one pully turns on the compressor/motor. I'm not sure what it is. What do I do to fix my air-conditioner. Watching your video, I guess it's the clutch pull only one turns.
Reminds me of.. me when I am in my shop working. I talk to myself in the same manner. Kudo;s
First of all, I am no expert on diagnostics like yourself. With that said I just learned how to use my multi meter because of you. Now, I could really use your help. A/C stopped working during a miss fire on #2 - 2012 nissan altima 2.5 s sedan after I got thru putting on all new coils and plugs. Turns out a plug was bad. During the miss fire I broke a cardinal rule of driving while check engine light was flashing up to the auto parts store. Very violent experience to say the least. So what I've done... I have 13 volts coming out of the power supply lead going to the clutch. Clutch is free spinning from compressor, never had a problem with it. No pulley noise and pulley running fine. Clutch not engaging since the miss fire code, thus no A/C. I think it's something easy like electrical and not mechanical. Do you have any ideas for a guy just trying to do a little wrenching to save money with a little talent I possess.
while there are 13 V to the compressor clutch connector, that won’t account for possible voltage drop. easiest thing to do is apply battery voltage directly to clutch. if it doesn’t work, it’s your compressor. if clutch activates you either have a voltage drop on the wiring OR you have a shorted ground side control.
Your channel and content is so good but your ego is very hard to like. Thumbs up for content but you might consider it makes you look really insecure when you start mentioning other mechanics
You will have to choose what is more important then.
@@SchrodingersBox i like your knowledge but your personality and sarcasm is not a good thing. your smart but dont have great communicative skills..i have been and instructor for investigative teams and your deductions are instructive but your attitude conflicts with teaching..thank you for your channel regardless
@@angelsspirit335 Beta you make it sound like you are some kind of authority or something and I should do things like you do. I am an instructor too. Of 150K followers and MILLIONS of viewers. You should be asking me how I do it because you have not nearly such a loyalty base from your students.
@@SchrodingersBox sorry didnt mean to do anything but express maybe that day of that video you were over emphatic. you know your craft its clear. i didnt take any offense so i dont want you too either. great channel no matter!
What the...? This guy is Awesome! Anyone who quotes DEVO "When a problem comes along you must whip it" scores honors in my books. My books are great books too. Loves this guys personality, sense of humor and auto knowledge. He whips it real good!
Good job man. And thanks for sharing your video. You make the fixes looking easier
Why demean others? Still I thank you for this
Help please. First of all thanks for posting this great video. Here is my story. An almost similar story made you think AC Compressor Load but I'd like to give you more details.
2012 Malibu 2.4l
Engine was replaced and AC came on and off and then disappeared. At 1st, I thought LEAK...
Please let me point out I have basic or less than basic electrical diagnostic skill.
2 days ago, I decided to check for power and ground at the compressor connector after making sure all fuses and relay were good.
I found a broken power wire (green) at the back of the connector.
I connected the 2 wires temporarily, started the car and switch the AC, the clutch engaged and I could feel the air.
HAPPY I FIXED IT, i just need to connect wires well for good.
Yesterday, i woke up with this task in mind but since the wire cut at the connector was so small, I went to Chevrolet and purchased a brand new connector.
THE BEGINNING OF MY NIGHTMARE NOW.
I cut power and ground wire and, despite trying to be careful, I connected the wires to the wrong sides of the connector, not sure, but I had ground and power at the end of the Compressor connector. Plugged it, started the car and fuse blew. Replaced it, tried again fuse blew 2 times more.
I tried to plug a bi directional scan tool but it would not connect to the control module; it is as if, my scan tool is not plugged.
My neighbor put a wire on the ac clutch fuse to bypass it and I ensure to reconnect the power and ground wire like they are supposed to be. Scantool still can't connect.
IM VERY CONFUSED AND THIS IS WHERE I NEED YOUR LEAD.
1- My first thought is AC CONTROL MODULE BURNED DUE
(I do not know where the AC control module is located).
The AC control panel buttons seems to be working.
2- Could the AC Compressor be burned by the wrong wire connections?
3- Since the fuse kept blowing before we bypass it, I also thought another broken wire but I don't know since compressor clutch still wont engage despite bypass.
4- I get 5V at the AC Pressure switch; could the AC pressure switch be the issue?
What do you think?
Thanks for reading my novel
Before the cream sits out too long... you must whip it.
you're my hero. i want to do what you do, now. i'm legally blind and can't legally drive but i LOVE cars and fixing things in general. since i get disability i don't have to work but i can't sit around all day watching gameshows. i'm tempted to post on craigslist for free car repair. advice?
Well for what it helps i am legally blind- completely blind in one eye but luckily i am correctable to 20/40. My sympathies bro.
20/80 optic nerve hypoplasia. how often do you get to hear "you don't seem like you're blind"? it's precious. my sympathies as well. you're a genius and i am forever grateful for your youtube series :) keep up the awesome work!!!
You should be a Radio Personality on Rock 103 FM lol you rip in to people so calm like...
I like your perspective on diagnostics on a automobile!
Arrogance is definitely not a way to go young man. Check your ego. You can do things without putting others down.
As if you have some kind of authority. Checkyourself I wreck you for looking hypocritical
My name David from Houston,tx I just want to say thank you.... My gal Acura ac went out... I don't know much about ac system until I saw your video... My gal was panicking and about to call a mechanic...I ask her to let me check it out...It was a brown fuse... I just imagine how someone could be paying much, for something very simple... thanks
I'm here to make this Video cuz I love to here myself rattle on n on .although I appreciate the help
No I am here to eliminate idiocy in this world. I see I need to focus much more on you specifically. If you would THINK for even just a second, if I just wanted to hear myself talk I would not have to make information you found valuable.
Idiocy. It's overwhelming.
i like your methodical approach
Me too! Works every time ‘n
Fantastic job thanks, where are the links to the other videos ?
Great fix buddy. Do you have a catch phrase now at the end to whip it good? :) LOL
I passed 3 ASE's on Monday, Brakes, Electrical, and Powertrain diagnosis. Those tests were brutal. Days later I was still suffering from the mental exhaustion of it. I'm usually better on paper than in the real world, but they'd throw so many weird things in on electrical issues that you wouldn't expect, but all that thinking actually made me better on electrical than I was before the test.
There were a few things I didn't get quickly before the test, that I do no, including how you went to an outside ground to see what was going on with the wiring passed the relay. Brilliantly simple. The kind of thing that I think was on the test, well, never. However, I'm sure thanks to you and other information, which has helped me get better, your simple test was the sort of things I thought of during the test to simplify complex circuits.
ASE prep and tests themselves all suggest to test for issues like yours with the circuit of and with ohm's of resistance. They do teach correct load testing, but then fail to use it when it's best. What if the circuit is always hot? Then you'll potentially damage your DVOM (they liked to call it a DMM) when testing for ohms when voltage is present!
Glad to have you back in whatever capacity you can be here. :)
Some non-digs on the ASE...the test exudes pressure to look to relay's and testing through them as in real life I do find that an effective way to find issues...
Another non-dig - studying alone wouldn't have got me to pass, and they do require at least 2 years of experience. Hmmm, several years of 20 hours a weak DIY to them doesn't count as "professional" experience. Heck, I counted it anyway. Thankfully, I have a business to house my experience under.
I love when i have a issue and see you to solve it here. I just started working on my car 3 weeks ago and this is the only thing that makes sense to me Thank you!
I can't see and I thought I was doing this
my mechanic has replaced all components. still not working properly. he advises the compressor is not coming on because the circuit blew and i need to replace the engine computer.. He did test system and it holds freon. compressor is new. the max light does not come on on the switch. my question is how do i know the switch is not the problem
You just check for continuity at the switch. Or simply bypass it and see if it works.
Glad to see you posting again. I miss your videos the most out of all the UA-camrs.
Why everyone that does these awesome videos not located in Houston Texas? Excellent video
I will watch every video you make sir! cant thank you enough.
Exactly.
You make great videos they're very informative ,thanks keep it up
Great method. Please dial down the sarcasm and disrespect.
Thank you for posting this. It is going to help me trouble shoot my air conditioning on my silverado. You put it so simply i have the confidence to do this myself now. Thanks! Oh yea.... Dont let the nay sayers get to you. You got a gift , share it!!
"Straight to the point"? Then his point is obvioiusly NOT to explain how to fix the problem, but to, as he himself sayS: to make fun of those who don't know what they're doing. Much of this arrogant blowhard's time wasting is spent on just that, ad nauseum.
See how you keep watching all my videos though. That's the point. What a dope ROTFLMAO!!
Great video, but do you you have to put put down other UA-cam channels and/or people that comment? Youre putting it out there, so you shouldnt expect all positive responses, man. Very arrogant......sorry
Ummmm, how is this any different than what you just did? Why are you not holding yourself to the exact same standard, especially considering you aren't contributing anything while I am?
Please explain. Because you sound both ignorant AND incompetent to be quite honest. Just giving you constructive feedback man.
Im hardly arrogant, just watching your video should tell you that. And as far as incompetant, how can you tell? Ive been doing this a long time but I do watch videos to help me with some of the new vehicles. Saves me time. All respect, but yours wasnt especially helpful, turned it off early, man. Lol!
All i’m saying is I am holding you to the same standards. That’s all. You are welcome to learn from me but you don’t set the standards.
No you fail to understand. I set the standards. thats why i deleted your last comment. Got it yet? Now be a good little intern and keep learning. Otherwise i’ll set them even higher.
Why have you chosen to be so defensive with potential subscribers comments. If they all seem to you like rubbish ignorant kids who are just posting dumb comments on your videos than why not disable the comments altogether? Would seem wise given that after just reading 2 to 3 of your back and forth replies to comments has me understand why it is that your channel stands where it's at. If you could ignore your unnecessary catty need to speak negatively on other specific yt mechanics, your videos are informative and would be helpful to the less inclined in auto mechanic repairs.
Now with that I couldn't support your method or belief in teaching, so I'll be sure to avoid your channels videos in the future which I can guess you won't be bothered by that but also I'm pretty positive that I'm not the first to think this way.
brilliant tutorial sorted my air con out. thank you
This is exactly how a professional mechanic shop does things, and also they hook up a computer to determine the problem, a diagnostic test is ran also
Rev up your engines! lol - First 5 minutes of nothing but rambling on about nothing! The first thing I and most people do is go to is the fuse box and swap relays, duh! Not hounding or arm chair diagnosing, but that sort of diagnosis is simple and yes it is obvious to just about everyone!
Vs scotty rambling about nothing for every video.
life is simple for you when you’re just a basic bitch ain’t it? Ignorance is definitely bliss.
Your entrance rant was hilarious
The video is appreciated, but really? The condasending attitude is really not necessary.
Your comment wasn't necessary either if you think about. Let's keep equal standards eh?
15:30 you did a great job.
Awesome sauce! Once again, you've whipped it! Carry on...
I’m learning and working on the electrical system is very hard for me as a headache but you make a look so easy and fun thank you very much man👀😎
I bet you're fun at social gathering. You're smart, I'll give you that, but I could do without the "holier than thou" self righteousness.
Seem to me you are the one with that condition seeing as how you judge me without providing any value like I do. Really ironic if you ask me.
@@SchrodingersBox I use my knowledge in diagnostics and repair daily. I don't make videos calling people hacks. I don't talk down to anyone that does things differently than I do. Unless they act like you. Then I tell them the same thing I told you. Your videos would be better without the condesention, lil fella. Find you a woman get laid. Maybe you'll lose the attitude. Have a nice day, buddy
Yeah maybe your mother isn’t enough for me. have a nice day yourself. I’m busy with my 120K subscribers that recognize the value i provide. again, what exactly do you provide?
Never mind i just checked what value you provide to your 4 subscribers over 3 years on youtube ROTFLMAO!!!! Yeah if i need any advice on how to run my channel i’ll be coming to you..... NOT!!! rOTFLMaO!!!!!!!
I don't usually put anything on youtube. I actually run a business and make a living doing auto repair and heavy recovery. I actually provide honesty to my customers and help our schools train our new guys coming to the field.
You sit on your little chair in your little garage diagnosing things for people.You said yourself you don't even fix them. lmfao. What a joke. You can diagnose them but you're not competent enough to do the repair. I've ran in to a lot of folks like you in my day. We call them posers.
Wow! Your in a very bad mood. Go get some sleep and take a shower. Geeze
Love, a Hack
Wow are you kidding?? He filed it didn't he? Sooo the chill, no idea what's wrong thing appeals to you
No bad mood, he's just tired of folks who lack the skill and knowledge he has second guessing him. Plus you should ignore that and appreciate his method.
Matt, fun and good diagnosis, as always =D
A hug from Spain my friend.
Always good to see you Pablo!
Agreed. :)
You forgot the first step: Verify the complaint.
I don't need to- I can see the clutch does not spin. It can be inferred the complaint is valid.
I have a 2000 Jeep Cherokee i ride and a parts jeep 96 Cherokee Country. Ok My ac compressor locked up on the 2000 . it wasnt working and was making funny noise b4 it finely locked up. So i knew the one in the 96 was good so i took the 96 off but the lines attach different on the 2000. where they go in the main back on the 96 and on the top of the 2000. So i changed the back out so i could use my 2000 lines etc. I put new oil 4 oz. ruffly maybe a little more and it took the oil fine but will not take the freon. I paid a guy 25 bucks to have it vacuumed and had no leaks but it still wont take freon. could a bad AC pressure switch cause it not to take freon or maybe the condenser is stopped up when the compressor locked up and iit got metal in the condenser and stopped it from taking freon or what... Im at a lost and dont have much money...but I need my ac bad. i have a hard time breathing when i get really hot... So all help appreciated...
not just adding refrigerant but one that contains stop leak and oil. adding more oil makes evaporator heat transfer worse
The stores love to sell that stuff.
I got the very same problem with a 1997chevy S10 V6 , I thank for your help , you're awesome 😇😇😇👍👍👍👍
I have watched some of your video before, but not this one. Some of your explanation is really help, but if you can go straight to the points and do less talk, that will be perfect.
I don't make these for you. I make them for my fans. Sounds like Scotty Kilmer is more he type of channel for you. You're on the wrong channel.
OK. that's just my opinion. His videos are too short. lol
Paul Wang almost everything he said was straight to the point. Without his words, you wouldn't know what he is doing. So listen and shut up.
you want him to be you? That him at his best. What's wrong with people nowadays. No patience at all? It's a video. ffw if you want, or increase the speed of your video in setting
+TimezUp23 get a life asshol.
i love your diagnosis steps. They help me in Real life situations i appreciate you.
Yes. scientific approach works for ALL things, not just cars.
Denis Lau On o
surprised eric o from south main auto hasn't commented yet! or ivan
They turned it off soon as I brought out DVOM instead of test light hahahaha. Actually I was going to do all the tests using a test light just for them- But at the same time, I also wanted to do this diagnosis conclusively the first time lol.
I generally grab my test light when it's the better test for something or I can't find my DVOM. :)
But then...I'd have to have misplaced my PowerProbe as well, as sometimes I hook it up in ingenious ways just to see the voltage my dvom would have shown easier. Ha.
Good job and a great video explanation. I repaired mobile a/c professional for 24 years and I have to say your thought process is right on. Thanks for the videos.
I like this guy he talks the talk but he walks the walk.
Nicely done Mat. Reminds me of my problem. An Aircon that runs, deactivates and activates again.
Not new. Used to be fixed just by putting contact spray on the pressure switch connectors. Looks like I have to go there again.
Some genius put the Switch directly into the airflow of the engine and aircon cooler. So it gets blasted by saltwater every winter. And for some reason after 27 years it is taking it not that well anymore.
Ill see if I can reproduce the error while not sitting in the car. If so i'll pinpoint the defect and think about a solution.
Bets regards.
Benjamin
PS: Did I miss the origin sensor solution ?
Blair witch project quality
If that means its good- then you're right.
xD ok i genuinely laughed at the Devo joke
some local said ; $50.00 for a tune up on the system. It just stopped on the way home from work. 5 years ago. what about this low pressure switch going bad. I have a paper clip to jump it across. Could that really be it? 92 4.0 cherokee.
Thank for telling me to look and look compressor was not kicking in. Work fine one day not next check R134A ok well thought was But checking cables found a rubber pipe spilt cut 1/2 inch off compressor worked then need to fill system nice chilly for our 3 days of summer we get in UK
In the run up to 12:29 in the video you had the voltmeter across the load side relay contacts. You would be unlikely to see a potential difference between the two relay load contacts - even if the load was passing current. With an open circuit as you had, the relay load side terminal would be floating. That is why you didn't read a voltage. This of course changed when you rearranged your meter leads to reference to the engine (which is grounded). If your load hadn't been floating the load current would tried to pass through the DVM.
Hello sir. My L300 fb van is a dual aircon front and back. Is it possible to condemn back aircon without changing smaller compressor or condenser. Is there a problem if i only use front aircon and compressor at ease design for dual aircon? Thank you
My air is not working.im overheating
I watch video but kinda hard to follow. Wish you could explain it a little easier for women. Nissan dealer will charge me 600.oo..I hope I can find someone to watch this and figure it out. Thanks for video
When you haven't added refrigerant in 10-15 yrs, it's prolly a safe bet. 😆
Some people do not have any mechanics build I do not know how to check how big electrical system on an AC system so when you go to jump start an AC system you have to make sure the you have the correct wire for the positive and the correct wire for the negative when it comes to the pressure switches especially a three wire pressure switch do not put power directly into the wiring harness on the pressure switch when you have the ignition switch on you can use your voltmeter and ammeter to check to see if your having voltage but do not feed voltage into the wiring of the pressure switch for AC compressor wiring but you can jump start the AC compressor disconnect the wires from the AC compressor if you jump start the AC when you're disconnecting any type of electrical connections turn off the key these are simple things that will help you I hope my information has helped people some people don't know that you have to shut off the ignition switch before you take off I'll kiss him back any type of connection I hope my information has helped you everybody have a good day yes you need to know the theory of how the air conditioning system works and there are a lot of good videos on the internet to show you how to do things
glad to see you back bro fun video
Love your videos! you have fought me a lot! when are you going to do a video with steering? I have an issue with a steering torque sensor on a 2005 VW golf
Good point made for the visual inspection! You have a problem, as a fact, so u batter start examin the system by overruling the posible problems. Thats the only way to find t problem, everything else is a waste of time!
I have a friend that does the "Visual Inspection " for ours.😄
But on the end is me that fixes all his problems.
Thenks for video, it was educational!
Ya nothing against old scotty Kilmer but hes old school only basic and I just cant stand the dudes voice can't watch any if his videos even if he was talking shit about Biden the whole video I just couldn't sit thru his stuff
Interesting personality. Like your tools setup. Always looking for good tools. Great way to test relay. Had the same issues so this helps. I dont do ac but cars are old and local mechanics have failed me too many times.
Oh sure! now you are the FAVORITE DIY'er! You should also say/write with that "on UA-cam." haha!
Looks like he's been sabotaged by the gremlins.
Thanks for the video !
I like your attitude but I still am learning to work on my personal vehicles. I am guilty of the “replace until you find the coconut” methodology. Keep up the good work and we will keep watching and learning ❤️
You are wrong.... they dont add refrigerants. They add new sparkplugs then refrigera🤣🤣🤣
Dude you talk too much!
Yeah most simpletons say that. I have over 100000 people who subscribe to me and what- 15M views and you only have 3 who subscribe to you. You should put together from this that you ALWAYS talk to much because NOBODY cares what you have to say--- pretty much the diametric opposite of me.
BTW I know you're a simpleton because you failed to indicate how I did the diagnosis wrong.
@KayEh Because I get paid for it. Every time you comment, its a view, and I get paid.
I can totally accurately diagnose the problem just by the sound of the 1st phone call ring.
Thank you very much! I was ready to buy a new compressor. It was only a bad relay. AWESOME!!!
One trick to release the ac clutch u can wire from ur battery to the fuse panel with clamps and it turns the clutch over
how would that work when the clutch is ground side switched?
sounds like my problem too.. Its not just one car your fixing there but i dont have to tell you that. thanks for your time.
You could take the compressor relay out...remove the cover and push the contacts close..or jump the wire's where the relay was, and that would confirm that the compressor clutch engages.
Why would you want to do that when load side feed was confirmed after the switch? You already know that power is there and the clutch still won’t engage due to lack of feed.
@@SchrodingersBox when you first walk up and start to work on it...pull the relay and jump it and that tells you that the compressor clutch works...and its from the relay back, or whatever controls the relay, that is what Im saying....The wiring to a compressor is not always as easy to get to as the one you had.
I did that- with the test light. Thats how I diagnosed the problem as open load side feed after relay.. If you just jump the relay and the clutch doesn;'t engage then how do you know the location of the open? The test light is way better because it tells you where as well as if.
Pls sir, i am having a problem fixing a coastal bus with ac issues (Name: Joylong) and current does not supply to the compressor wire,
I have traced the wiring system but i didn't see anything, i also used a diagnostic tool but the diagnostic tool didn't detect the name of the vehicle
Sir i need your help, i have even changed the relay that controls the compressor and it still did not work.

so a visual inspection found the problem...
visual inspection ALWAYS finds the problem on ANY issue. The science is in knowing exactly what to look for instead of acting like a lost dog.
Off your med's again?
Thanks for this helpful video; excellent logical approach to an a/c fault. But I don't understand why a cleanly cut wire caused a working a/c to suddenly stop working while driving. Wasn't it more likely to have been accidentally cut during an unrelated repair, causing the a/c to not work since then?
Yes good point. The severed wire was the result of a incorrectly made butt-connection on a previous repair. It appears the crimp severed through the connector and it broke “clean”.
