I think the HVAC controls are vacuume operated so you'll hear that "psh" sound regardless. I'd test the relays/fuses first, then look at the compressor. There should be a view port to check for freon somewhere on the low?|high? line?

if you have refrigerant in it and it still doesn't work...try to see if you have power going to the a/c...if you do and it still doesn't work check to see if you have the a/c malfunction code, and clear the code...that's what happened to my car...

Hmm. Doesn't sound like the relay then (which btw, you'd just take it out and take a piece of wire and jump two of the terminals--the diagram on the relay would tell you which two). Sounds like compressor is shot. I have two sitting in the garage that worked when I took them out. I set them up with their holes plugged to keep debris from getting in them. PM if you're interested.
