I just got an Aveo 09, and the A/C does not work (I knew prior to purchase) but the thing that gets me if everything seems to function.

Compressor kicks on, fully charged, no leaks per my mechanic I've gone to for years and trust. But no cold air comes out. My mechanic is not certified on A/C systems, but was able to tell me its charged and has no leaks, I checked the fuses myself.

I have looked and other posts seem to describe the same problem, but seems none of the compressors worked in other posts and mine does, so Im thinking a different problem.
