Hello! I for the past few weeks have not had AC in my 92 Camaro and wanted to replace the Compressor relay first then try the pressure switch next. Well i'm not sure of the location of the relay so maybe you guys can help?

What do these 3 relays control? From a few posts I've read, it's the fuel pump, compressor and cooling fan. Any help would be great!

 

I just had my car worked on in S. Fla. This is what I got for 75 bucks.
Evacuated all the refrigerant and replaced with the correct amount.
Trouble shot the entire system and checked for leaks
Evacuated the system again, made the repair, and refilled the system.

For that price and service it was a no brainer. I usually do all my own wrenching
