General Information

The purpose of the heater is to supply heat to the interior of the vehicle. The vehicle operator can determine the level of heat by turning the temperature switch, located on the HVAC control module (IPM), to any setting. The temperature control can change the vehicle's air temperature regardless of the HVAC mode setting, heater or A/C. The vehicle passenger can adjust their temperature by adjusting the right air temperature switch. Back seat passengers can also adjust their temperature settings by adjusting the temperature switch on the auxiliary IPM. Both passenger and back seat passenger temperatures can be offset 4°C (7°F) cooler or warmer than the primary setting.

The IPM provides power and ground to the left air temperature actuator. The IPM receives power from the rear fuse block through the ignition 3 voltage circuit. Ground is provided by the ground circuit.
