Heater And Defroster:

SYSTEM DESCRIPTION
The heater system provides heating, ram air and power ventilation and windshield defrosting. Outside air is drawn from the plenum at the base of the windshield into the heater module by the blower fan. Additional outside air, called ram air, is forced into the heater module by the forward movement of the vehicle. Within the heater module, the air is heated as required, then routes through ducts to the proper outlets for discharge into the passenger compartment. A control assembly in the instrument panel allows the operator to control blower speed, mode of operation, and temperature of the air coming from the heater system.

The heater module contains components that heat the air flowing through it and direct the air to the proper ducts and outlets. These components are enclosed inside a two-part housing. The front housing mounts to the front of the cowl panel in the engine compartment. The rear housing mounts to the rear of the cowl panel in the passenger compartment under the instrument panel.
