AC Not Cooling
Hello everyone: I have a dilemma with my 2002 C5 AC - until this afternoon, the ac was blowing cold air and working perfectly. When I drove it this afternoon it blew only hot air. I examined the compressor clutch and it was engaged constantly, not cycling on and off as normal. I then went and rented gauges to check low/high side pressures at 2000 rpm and 78 degrees ambient temperature. The low side read very high at about 112 psi and the high side was about 145 psi. I’m desperate for input into what the problem could be. Temps are in the 90s and 100s already and summer is just beginning in Arizona!😎🌵

My local mechanic -- not a corvette specialist, by any means -- just charged me around 3.5 hours to change my compressor. If you can get it replaced for anywhere near that, I recommend tearing your pocket to get the money out...
