Air Distribution System

Air enters the heater and ventilation system where it is heated as necessary before being sent to the proper ducts and outlets for discharge into the passenger compartment. Within the heater case, doors guide the airflow in response to the positions of the temperature lever and the mode lever in the heater control unit.

DUCTS AND OUTLETS

Air flow control doors, operated by the mode lever, route the air (either heated or unheated, fresh or recirculated) through various ducts and outlets. Ducts include right, center and left I/P ducts, right and left side window defroster ducts, windshield defroster nozzle duct and a center floor duct. Outlets include right, center and left I/P louvers, right and left-side window outlets, and right and left windshield defroster nozzle outlets.

BODY VENTILATION

Figure 2:

The body ventilation system provides the passenger compartment with fresh, outside air which is routed through the same vents as the heated air.
The primary fresh air intake is located within the cowl panel. Air is drawn into the interior of the vehicle from the intake grille and is drawn out from the ventilator outlets in the body rear panels (Figure 2).
