I've got a 99 Chevy Blazer with a 4.3 sitting in the driveway. Trying to get it together to sell and found a problem with the A/C. The blower kicks on fine but it blows hot air. Found out that the compressor wasn't kicking on. I got an R-134 can of refrigerant with the gauge on it and hooked that up. The pressure was ok but a little low. I added some refrigerant anyway and the compressor started kicking on intermittently. It's on for 2 or 3 seconds then off for the same amount of time. The air doesn't get colder though. Anybody got any ideas? I don't want to add any more refrigerant cause the gauge says the pressure is already high. I also noticed that the gauge pressure went down when the compressor kicked on, then rose again when the compressor was off. Is this gauge very accurate and does anybody have an idea what is going on?
