Hello. From what you describe, it sounds like there may be some sort of issue with the clutch pressure / cycling switch. These switches are responsible for activating the compressor when they detect that the pressure is at or temperature has reached a certain threshold. If they are not functioning properly, or there is an issue with the circuit or wiring, then they may cause the system to malfunction. I would start by testing the switches to see if they may need to be replaced and going from there. If you need help having this scoped out, a certified expert from YourMechanic can come to your home or office to diagnose the AC system and guide your through a repair.
