AC not cooling. Recently added Freon, not still not cooling. Checked pressure and found to be too high! Relieved some pressure , then too low. Replaced low pressure switch and tried to add more Freon only to get high pressure again. Please advise on what I’m doing wrong or what I need to do. Thanks -
1st hope I did this right, my apologies if not. Haven't been on here in years. So ice replaced my ac clutch and it went back out. Replaced the compressor with the clutch, Ac worked for awhile and compressor wouldn't come on. Hotwired the relay to get the compressor to engage. That worked for awhile. I've since replaced the auto AC control head the dash part under the radio. Still nothing from the compressor until I stick the wires in the relay hole, that starts the compressor but it won't take freon. Not sure, it maybe full. Also the relay has been replaced. About the only thing that hasn't been replaced is the high pressure switch. Any clue on what the problem is? I'm at my wits end with this. I love this vehicle but every Yukon and Tahoe I've had in the past has been a pain in the butt with heating and air problems. It's hot and I'm desperate for help
