Being an autodidact is the best way to learn IMO. I was an electrician before I started working on cars so this kind of stuff all makes a lot of sense to me already. The thing that I had to learn myself is how all these electrical components are actually controlling stuff in the car like the engine or transmission. Learning it yourself is great because you develop greater insight in specific things than if someone were to teach you ;)
@@@Diagnosedan Now, when I found out that you're autodidact..., I like you even more!!! Amazing stuff..., like usual... :-) I love to learn from you. And funny thing, one of my nephews asked me this morning if I know what could be the problem with his car, same thing like here, only it is on the right side. I knew I saw this title in your videos, just got back home, found it, watched it and now I'm sending the link to him in...Europe... Thank you. You the man..., again!
Hi, Dan For the past year, I’ve struggled with my 2011 MK6 Golf regarding the issue you address in this video. Last winter, I had a problem with water getting in my car at the passenger’s feet area - apparently, through some clogged lines that were supposed to drain the water from the sunroof under the car. At about the same time, I realised my car won’t heat the passenger area at all, no matter what settings I used for the climatronic. Went to a mechanic and he took my whole dashboard apart, he said it was an issue with the heat core being clogged. My car was finally blowing heat into the passenger area. Exactly one year later, I realised my car was doing the exact same thing - only blew cold air in the passenger area. Went to the same mechanic, he told me he unclogged some lines / something (no dashboard removal this time) and the car blew nice, hot air through all the air vents...for a couple of days. I’m now in the situation that my car blows cold air through ALL the right side (passenger’s) of the car (including the back side). I didn’t reach a VAG COM diagnose tool until now, but I suspect there is no fault code about this. What do you recommend me to do first? Car in discussion is MK6 Golf, 1.4/90kw, Climatronic, LHD. Thank you!
I was definitely enlightened a notch more with your explanation & break down. I truly like the manner in which you go out of your way to set up your own demonstration, to really drive the theory home.
Dan another fantastic video. I'm also enrolled in Paul Danners on line instructional class and between your explanation and Paul's you have visually cleared up all my questions of the flow of electricity thru positive and negative flow resistors. It's great to see an opposite flow as the resistor heats up the resistance drops and voltage flows to ground. Really enjoy your video and the visual explanations. Cheers
Excellent explanation of how the thermistor ckt works inside of the PCM. You do such an excellent job of explaining the way things work Dan! Loved this video!
Thanks Dan, this video helped me to fix the cold air blowing on driver side on my RH Audi A5 2010. It was the thermistor in the side vent that was faulty, wouldn’t have been able to diagnose without your help. 👍🏽
Hi Bap Athwal. I have audi A5 2.0tdi, 2015. Same problem like this one, cold drivers side and warm on the passengers side . It is hard to find the right diagnostic , so everyone is guessing in my place. Please tell me, so you had the exact same problem as from the video, i mean you fix it with the sensor replacement? How much time and money did it cost you? Thank you !
@@ivicaslavkovski3251 yes I had the same problem as in the video. I removed the thermistor got the exact part number printed on it and looked on eBay, I got a used one for around £10. Make sure it’s the same part number otherwise you may have issues. It’s easy to remove and replace, just twist it and lift up and it comes out. As I done it myself it was only the cost of the part. Hope that helps.
You simplify any issue to make it easy. love the vids please post alot more more frequent! Also love the communication diagnostics since they are never simple but your vids have helped tons!
@@Diagnosedan Right now ive got a 06 c55 amg mercedes. Car had a new battery installed 2 months ago now esp off, no communication with abs, & stuck in first gear
Hi dan, you know the thing is this: i've write a manual to go along with a lot of explanation with the intent of touching every subject needed for diagnosing. So i know how fast you think and how much is hard to explain everything so slowly and throught. I really appreciate your efforts :)
Thanks that's a great comment! It is hard because there are viewers watching of all levels, so i don't want to go to fast or deep for the people who are starting doing diagnostics and i don't want to make it to boring for the experts!
You are doing a flawless job going through the mind processes behind diagnosis. Hope i made myself clear, it's been a while since i've wrote something in english XD
I have cold air on the passenger side with heat on max. Tested both sensors and both passed. Switched them just in case. Still no change. Not sure where to go next. Thanks for the video. At least I knew what to rule out. 2013 Passat TDI SEL.
Thanks nice explanation 👍 Just want to sher my car story Toyota Estima 2009 acr50 driver side stuck on cold took me 2 days to dignosed found the Ac wiring harness is faulty replaced with second hand from wrecker yard now everything works fine
Another good video. I was expecting to see a low resistance on the bad sensor compared to the new sensor when you did the Ohm test because the sensor was reading a high temperature.
Thank you, Since you touched on the VW , I hope to diagnostic everything related to the Touareg Transmission and gearbox delay and kicking when changing gears No. 1, 2 and 3 My Regards
hey watching form australia! I love your videos honestly im a mechanic myself worst at diagnosing these issues cause our education here isnt about learning its about making companies money! so im learning heaps from you! wow bit mind boggling at the start but awesome content :) keep it up! wish i had a mentor like yourself!
What I like to do when diagnosing sensors like this, is to see if the read-out changes when I disconnect the sensor. If nothing happens, then the sensor is toast. Also, if your scan tool knows the range of the sensor, and the read-out is spot on the outer limits, you can tell if it's a sensor fault, wiring, or (in the case of an AC pressure sensor) the gas pressure is too low.
A useful video - remember that automotive thermistors are usually NTC (negative temp coefficient), so resistance falls as temp rises, allowing current to flow to ground.
Thank you Thank you!!!! I'll trying my new thermistor first thing in the morning. Fingers crossed, but I believe it's safe to say you most likely saved me alot of time and cash! Thx sir.
thank you so much for going into great details on how the systems work... for us guys really wanting to understand how it all functions is key.. thank you
Thank you DiagnoseDan ! You have been of great help! I had the same problem and swich the passanger side senzor with the driver one and the problem changed sides.
Nice work, ive had a similar problem with a MK7 GTD, checked the temps on the Diag, both reading correct temps, also checked the temp control module as thought it could possibly be a broken actuator, but that alos seems to be doing its job, tried recalibrating, again no problems seem to surface, i have two fault codes which are B10CD00 and P171900 . just wondered if you've ever faced this issue before
Fantastic channel! Im studying bachelor/master autotechnology in Belgium and this helped me a lot to learn more about the NTC resistor ( thermistor). Keep up the good work! Greetz, Cédric
Love the detailed breakdown in the video! I am looking for a solution on my mk6 gtd 2010. All blow stages work, same fan speed. But I can get no proper heat. Vent temperature reading are Left 26°C and Right:23°C. What could be the issue? Also no error codes
I guess it would be a good idea to check all temperature sensor with the fan off after the interior temperature had a chance to equalize because I have seen on some Volkswagen that the heater core can produce the same problem and also the blend doors on a Dual zone system.
Well thank you so much for the detailed explanation. You are like the Bill Nye of auto. Perfect. This is exactly what my 2015 passat tdi is doing. Can I assume the location of these failed parts is the same on my car as the one you have described? Thank you so much.
I don't know if you have current videos, however I find it interesting how knowledgeable you are.

Hey guys so I have a question, as I was driving(road trip California-Illinoi) in my 2012 GLI, heater started blowing cold air on passenger side vents and middle but not the driver side vent by the door, how can I troubleshoot that ?

Hello Dan That was great video. In my car i got cooler air on passenger side both on face and windshield. Is there is any sensor on windshield vent too or not? And can you suggest where to buy sensor from? Thank you
My car: you can choose whatever temperature you want and you would get always the wrong temperature: Heat in summer and Cold in winter. Its an old A4 B5, I'll have to fix the heater core but disassempling the whole dashboard is quite challenging if you don't find the instruction on online. Or even on elsawin!
