1996 B5 A4 2.8 12V AFC quattro auto.
The AC was never working since I got the car.

Not sure if compressor, low pressure, condenser or other leak, module is causing the problem.

Is there a way to narrow it down?

With temps below 50, would the compressor kick in?

Are any of these HVAC codes related to the physical condition of the AC system?

Do a google search for "Ewok_Fetus". He was on another forum (the Zine I think) and I read a three page thread by him where he walked a guy through every step of it. The knowledge he has about Audi HVAC is sick.

 

I'll seek him out. Thanks.
