A3 VW 2.0 A/C blows hot and cold

Does it tend to turn hot if you are accelerating hard or driving very fast, and then return to normal when you are at a steady speed or slowing down?

It's a 2.0L....it isn't capable of going very fast! LOL

Does that mean there are other thieves besides dealer. I bet you would have paid less at the dealer? I need to know if the compressor is still running when it ain't cold? look to see if the center of the clutch is turning.

I would suspect a relay somewhere. I had the same/similar problem with my 91 Passat. It was one of the relays in the engine compartment. I found out which relay when I was troubleshooting my AT shifting problem. No a/c and no a/c light coming on in the switch. Of course I also had a problem with the blower relay on the inside of the Passat, but that is another story. ;-)

Try jumping the positive side of the compressor to see if the a/c starts cooling. Yes hook a positive wire up to the correct compressor wire to see if the compressor starts functioning.

I had a problem like that. Check the 2 wire temperature sensor coming out of the head. This cuts the a/c if the coolant temp gets too high. You can jumper the connector with a paper clip and drive around for a few days and see what happens. If the a/c works correctly, replace the temp sensor (~$12, iirc). This is, of course, assuming that your car isn't overheating.

Thanks for all of your help, my compressor died on me about a day after I posted my message. The compressor clutch locked up and stalled my car, and after getting it to run for about 30 seconds my engine compartment filled with smoke from the clutch. On that note I was hoping that I could get a serpentine belt for a Golf that doesn't have A/C and bypass the compressor, anyone know if doing something like that is possible?

As for the dealer, thanks to Firestone I'm now out $400 on unnecessary repairs since they misdiagnosed my car. Dealer list price for a new compressor is $800, so if I can't get a belt that will bypass the compressor then I'm in the market for a new car.
