I just had some stereo work done, where they had to pull out the stereo and part of the dash on GT. When I got the car back, my AC dosent work, it blows hot air.... The Defrost still works, but takes a a few minutes to blow warm air. My question is: What could a bad stereo shop have done back behind where my stereo is to make my a/c messed up......?

What they obviously did is a bad job just screwing around with the cables and obviously disconnected something on the a/c unit. There really isn't much to say except to just take it back to them. Explain that it stopped working right after the radio was installed. If they don't help then you have to just take it to someone else. It'd be messed up to think someone would mess around on purpose, hopefully whoever did the job was just a moron.

They likely did not reconnect the electrical and vacuum lines to the HVAC control switch assembly, or were so ham-handed that they did not realise they had dislodged them.

Here is the control panel description and R&R document from the shop manual--however I agree with Synyster, bring it back and tell them to fix it...
