The AC went out on my 3.8L V6 Camaro the same way. Call Clearwater Automotive for the compressor. They gave me a used one, with a warranty, for $100 out the door. I took it to my friend Bobby's shop, Ultimate Auto on Lake in Largo, and he threw it in for like $200 or something. I don't like to fuck with A/C. I bet Clearwater Automotive has a nice used power window motor for you too.
