I am confident we can resolve your problem together. Pleaseunderstand that I don't know your skill level. In most cases when you have a problemwith the way the vehicle performs, specialized tooling is required to acquire computerdata/information or engine testing results. We didn’t build these complicated vehicles; wejust diagnose and fix them. Also understand that I can't see, smell, hear, or touch thevehicle either, so it may take a few replies to get to satisfactory results. I am also going todirect you with the fastest, easiest and most common things to check first. Please bepatient and permit me to do what I do best.I also try to give all of the information you may need, expecting a “positive rating” inreturn. I will also continue assisting you after you have rated me, if necessary. If thereis any reason I cannot get a positive rating, please let me know why “in advance”, so Ican go another direction for you. I am sorry you’re having this problem; I’ll help youthrough it.Below is my first answer or request for more information. If you do not understand it, or you need more information from me, or need me to go in more detail.
Before going any further what is the vehicle's issue with the a/c?
Any recent accidents?
any recent repairs before this ?
vin # please
sorry for the delay!!!
was a scan test performed on the vehicle (vag com needed) to see that there is no lockout code for a/c module ?
i can get that but was a scan test performed? the compressor operation is PWM . so the checking the wiring for 12 volts is not the correct way of diagnosis. scan tool is needed VAG COM
i will get that diagram but DID HE SCAN 08 CLIMATIC CONTROL MODULE WITH SCAN TOOL?
THAT SCAN MAY MAKE THE DIAGNOSIS MUCH EASIER AND QUICKER TO GET TO THE ROOT CAUSE!!
PLEASE HAVE HIM DO THAT IF HE HAS THE CAPABILITY!!
STILL WORKING ON THE DIAGRAM
