: A/C not blowing cold air - 2008 A4

Today I noticed that my AC is not blowing any cold air. It appears to only blow air from the outside. Last summer the AC worked great. Because of the hot weather in Chicago I decided to turn it on for the first time.

I don't think that it needs a freon charge, because of how cold the AC air was last fall.

I'm starting to think that the compressor is not turning on. How ever the vent system is blowing lots of air.

Any suggestions? I want to avoid a diagnostic charge from the dealer. My 4 year bumper to bumper just ended.

I appreciate any help you can provide me! :)

Hi! HVAC has pretty comprehensive diagnostics. Vagcom? If you do not have one, are you close to Barrington area?

Believe it or not, Before going back to the dealer, I showed it to a retired mechanic. He immediately found the problem. The connector to the ac compressor was unplugged. Last time anyone serviced my car was at my Audi dealership. Never going back there again!

Yes, I am close to Barrington.
