Compressor Clutch: Description and Operation
SYSTEM DESCRIPTION / Automatic A/CAuto amplifier controls compressor operation by ambient temperature and signal from ECM.
Low Temperature Protection Control
Auto amplifier will turn the compressor "ON" or "OFF" as determined by a signal detected by ambient sensor.
When ambient temperatures are greater than 1 °C (34 °F), the compressor turns "ON". The compressor turns "OFF" when ambient temperatures are less than -2 °C (28 °F).
