Compressor Control Module

The A/C compressor control module controls the operation of the compressor clutch in response to signals received from the A/C refrigerant pressure switch and the Powertrain Control Module (PCM). With the air conditioning system in operation, the A/C compressor control module performs the following functions:

^ Energizes the compressor clutch in response to air conditioning system request and upon determination of favorable system conditions for air conditioning operation.
^ De-energizes the compressor clutch in response to a high or a low refrigerant pressure signal (from the A/C refrigerant pressure switch), or a high engine demand signal (from the PCM).
