I had a similar issue with my 2016 golf R, strange codes but always the P0642 along with throttle sensor code and crank no start. I checked the reference green/red tracer wire on the upper map sensor and it's 5V. I unplugged the lower map sensor and both codes went away. Now I only have a map sensor code as you have and now the car starts. I'm waiting for the new sensor, hopeful replacing the map will fix the issue. If it does your video saved me many headaches. Crazy that this sensor fail will take down the whole bus but not even report itself.
Found your video while googling how to replace the blend door actuator on my father in law's Journey that has only hot air on the passenger side. I would have just replaced it, only to have it probably fail again. Now I'm going to add the stopper and not look like the idiot son in law I would have been when it broke again without adding this step! My wife and I thank you 👍 (even though she has no idea about any of this. Lol) you da man! Nova Scotia, Canada
Just wanted to say that this was a great inspiration for an expensive part (hvac door and unit) that is poorly designed and likely to repeat the issue eventually. I did this fix for my dad's cherokee and it worked brilliantly.
Adding the screw to limit rotation was my idea too and worked perfectly. I used #4-40 drill & tap for SHCS. 2 years later now drivers side needs the same fix
awesome fix. I had same problem on 2011 jeep. must of replaced my gear 5 x.. that screw was genius.. I 'd buy you a case of beer and pay you to solve that problem like that,, I got it fixed to $1200 with total Hvac replacement.... wish I saw this video last year... Great Job Alex...
The 5v ref is a series circuit inside the ecu, but parallel outside, so even if you test one 5v ref circuit outside the ecu and disconnect it the other 5v ref circuit is pulling the 5v down, because it's a shared circuit inside
you can improvised 12mm wrench. Cut the drive end of a 12mm and hammered it down to box wrench, flushed on one end and sticked a little bit on the other end..
Alex. I have a 2001 Dodge Grand Caravan that I did a HVAC blend door reset by holding the power button and recirc (I think) at the same time but now it won't come out of reset mode...HVAC lights alternately blink always, for the last two months since i reset. I even tried disconnecting battery and tied + & - cables together for 10 hours. Still won't come out of test. Any ideas how to fix that?
Hello how are you? I seen your video its great thanks so much! But even thou doing what you said it does not blow cold. What should i do now? Its the drivers side. I unstuck it and can manually move it with my hand, but the air is still not cold as the passenger. What could be the problem?
