A/C Compressor Clutch - Operation

A/C CLUTCH

The A/C clutch components provide the means to engage and disengage the A/C compressor from the moving engine accessory drive belt. A/C clutch engagement is controlled by the Powertrain Control Module (PCM). When the PCM energizes the electromagnetic A/C clutch coil, it magnetically draws the clutch plate into contact with the clutch pulley and drives the compressor shaft. When the coil is not energized, the pulley freewheels on the clutch hub bearing, which is part of the pulley assembly.

A/C clutch components cannot be repaired and must be replaced if inoperative or damaged.
