Defrost Lever

This lever controls the position of the defroster door in the heater case. In the "OFF" position, almost all air is directed to the floor from the heater outlet, with a small amount flowing to the windshield. At the "DEICE" (defrost) setting, almost all air is directed to the windshield. Moving the lever to any point between these two settings will split the airflow between the floor and windshield.
