GM Air Conditioning Pressure Switch Problem and Replacement!!

GM Air Conditioning Pressure Switch Problem and Replacement!!
Don't Charge Your A/C Till You Check This!!

In this video I fix an issue I was having with my GMC Envoy air conditioning system. While most of the time the a/c works fantastic, I was having a peculiar issue where the compressor would shut down for no good reason. Upon some investigation I came upon what's called the low pressure switch. This typical GM air conditioning pressure switch monitors the refrigerant pressures and if there's a problem it'll shut down the compressor in order to protect it. You can imagine, if this part malfunctions, the compressor will act irrationally. This irrational behavior is what I think was happing to my system. Those it wasn't very often, it seemed to happen at the worst times. I swapped the pressure switch for a brand new GM ACDelco unit and so far we've not experienced the issue again.
