Need help from the A/C guru's

[tatback]

I really need to know what part to buy. I have a 94 3.4 Camaro, the air blows but it isnt cold its warm. When I put two cans of freon in the car it blew cold for about four days then it went back to warm...also when I turn the air off it "hisses" for about ten seconds..what could be the problem and how can I fix it. Please help because the south florida summer is killing me.

sounds like you have a leak somewhere, get a shop (or DIY if you can) to add some dye into the freon mix and drive the car for a couple days, then you will be able to find out where it's leaking from. Also, a quick check of all valves/bolts to ensure they are on tight is also a good idea :)

You may have blown the seals in the compressor. If so, time for a new compressor :D . I have the same problem, and that's what happened to me

Same thing happened to me. I had to replace the A/C evaporator core. Take it to an A/C shop and have the system tested (~$35 bucks for me) and diagnosed. Fix it yourself if your able.
