The AC only works intermittently. It has freon and the compressor was changed recently. Can you please help me find a solution to this problem?
The Thermostat is sticking. Try moving the temp lever to hot and back to cold, and/or turning the knob to defrost and back. If that doesn't work try checking the the vacuum hoses/electrical connections/voltages. Had the same problem myself an a few cars.
Just realized you have a 99, my son's 99 oldsmobile, and my wifes 2000 regal both do the same thing, and it's probably the same control unit, these units are known for going out. But try the other first.
Robby, Thanks. I'm going to try your suggestion.
