Compressor Clutch Coil: Description and Operation
A/C COMPRESSOR CLUTCH COIL
The A/C compressor clutch assembly consists of a stationary electromagnetic A/C clutch field coil, a pulley bearing and pulley assembly, and a clutch
plate. These components provide the means to engage and disengage the A/C compressor from the engine accessory drive belt.
A/C Compressor Clutch
The A/C clutch field coil and the pulley bearing and pulley assembly are both retained on the nose of the A/C compressor with snap rings. The clutch
plate is splined to the compressor shaft and secured with a bolt.
The A/C compressor clutch components provide the means to engage and disengage the A/C compressor from the engine accessory drive belt. When the
electromagnetic A/C clutch field coil is energized, 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.
A/C clutch engagement is controlled by the following:
-
A/C-heater mode control
-
A/C clutch relay
-
A/C high pressure switch
-
A/C low pressure switch
-
Powertrain control module (PCM)
The A/C compressor clutch components cannot be repaired and, if faulty or damaged, they must be replaced.
