I have an 01 Monte Carlo SS with 5000 miles and the AC does not work.
I don't suspect anything with refrigerant pressure based off the mileage of the car. For some reason the relay will not close when the car is running (I did change the relay nothing changed). I don't have power but I do have ground from the body ground at the AC Compressor connector. The only way I get power is by manually closing the relay's contact points, then the compressor runs. All other fuses in the diagram are powered as well. Also the relay control at the PCM is closed (Grounded) as well. I would say all the parameters are met on the pressure side of the PCM to close the clutch relay control ground.
Am I fooled by the PCM, or something else? I really want to thank you for your time and help. I really appreciate it!
Eric
