Air Conditioning wont kick on

Has a shop checked the system for proper freon amount? Because if its low on freon the pressure switch won't let power go to the AC clutch, You can find a shop here https://repairpal.com/chevrolet-repair-in-decorah-iowa and check AC service prices here https://repairpal.com/estimator/chevrolet/monte+carlo

I got the same car with the same problem. I wired the compressor straight to the battery and the compressor turned on but it was shot. So all i need to do is replace the compressor and it will run fine. You can try wiring your compressor to the battery and it will most likely kick on. If your air conditioner works then nothing else needs to be done. leave it that way. but if it dont then you need a new compressor
