HVAC CONTROL MODULE

HVAC Control Module:

The HVAC control module regulates the operation of the various actuator motors. The actuator motors are used to move the mode, blend-air, and RECIRC. doors.

The control module is included in the A/C control head located on the instrument panel. The control head includes the blower speed switch, rear wiper and washer operation, front & rear window defogger,recirculation door operation, and A/C compressor operation if equipped. Refer to Instrument Panel Systems for Removal and Installation.

NOTE: The RECIRC. function on the HVAC control module automatically defaults to the OFF position after a ignition key cycle. To reactivate the RECIRC. function, the RECIRC. button must be repressed.

The rear blower speed switch is serviced separately from the control head.
