B1423

CIRCUIT DESCRIPTION
This pressure switch sends the appropriate signals to the A/C control assembly when the A/C refrigerant pressure drops too low or rises too high. When the A/C control assembly receives these signals, it outputs signals via the ECM to switch off the compressor relay and turns the magnetic clutch off.
