General Information

Ventilation Description:

The HVAC system provides heating, cooling, ventilation, ram air, and windshield defrosting. The blower fan draws outside air from the plenum at the base of the windshield into the heater case. The forward movement of the vehicle forces additional outside air, or ram air, into the heater case. The heater case contains the heater core, the evaporator core (if equipped) and the airflow doors. Within the heater case, doors direct the air flow to the proper ducts and outlets in response to the positions of the temperature and the mode controls. The heated or cooled air is routed through the ducts to the proper outlets for discharge into the passenger compartment. A control assembly in the instrument panel allows the operator to control the blower speed, the mode of operation, the air inlet position, and the temperature of the air coming from the system.

The body ventilation system provides the passenger compartment with fresh, outside air. Air is drawn into the interior of the vehicle from the intake grille within the cowl panel and drawn out through the ventilator outlets in the body rear panels.
