Exposure to engine heat, refrigerant oil mist, and vibration causes the connector locking tab to fracture and the terminals to corrode. A failed A\/C pressure switch connector causes the ECM to lose the refrigerant pressure signal, triggering \u003cstrong\u003eA\/C compressor cut-out\u003c\/strong\u003e as a safety measure — the system shuts down to prevent compressor damage from operating at incorrect pressures.

A corroded or open A\/C pressure switch connector is a common cause of compressor cut-out on Toyota vehicles. The ECM disables the compressor when it loses the pressure signal as a safety measure.
