DeVille V8-4.6L VIN Y (1998)
Air Duct: Description and Operation
Outlets
Four main outlets are located in the instrument panel, one on the left side, two in the center and one on the right side. A small amount of air is directed to
the side window defroster outlets and the heater outlet to cool the floor. The main outlet provides an air flow direction that can be controlled
independently. The outlet may be rotated and the knob in the center of each outlet may be adjusted to provide the desired air direction. Airflow from
each outlet may be stopped altogether by moving the shut-off lever, next to the outlets to the fully closed position.
