AC problems Check this out. Recharged the A/C system on the 95 formula last night. It blew cold air then. I get up this morning to check it and it is only blowing vented/warm air. I put a pressure gauge on it and it read high. So I bled some pressure out of it and put some 134a die in it and found no leaks. Why is it not blowing cold air?
If the compressor clutch is engaged and it reads 100lbs then it has blown valves. Chances are it is not coming on though. The only place these cars have hvac trouble is the compressor leaking through the front seal or where the case halves come together. Look at the rubber line from the header on the back of the compressor to the condensor and check it real close for signs of oil. That is also a trouble spot. Gm systems are real reliable except for compressors. Do yourself a favor and do not mess with rebuilt garbage from parts houses it is pure crap they give it a lifetime warranty for a reason; you will definitely need it. Spend a little more and put oe parts on and it will last another 10 years. It is not as hard to change as it looks.
