Caravan FWD V6-3.3L VIN 3 Flex Fuel (2001)
Air Conditioning Switch: Description and Operation
The A/C Switch is a momentary contact switch. Toggling the switch results in the A/C - Heater Control Module sending a change of state message to the
PCM to provide A/C compressor clutch activation or deactivation respectively. The A/C - Heater Control Module will only provide this request if EVAP
function is found acceptable. The Power Switch must be on to make the A/C switch active. The switch LED illuminates when the switch is ON. The A/C
Switch setting is remembered during power down.
