DESCRIPTION AND OPERATION

Ventilation System, Power

Outside air enters the air inlet duct assembly through the cowl opening and is forced by the blower assembly through the heater case assembly. The air passes around and/or through the heater core; is blended (if passed through the core); then directed, depending upon the position of the air discharge door assembly, to the panel by way of the plenum assembly. From there, the airflow is directed to the floor or to the defroster outlets.
