Function Control Lever

Function control lever can be placed in OFF, PANEL, PANEL/FLOOR, FLOOR, FLOOR/DEFROST or DEFROST position. The function control lever mechanically operates a cable connected to cams that operate floor/defroster and panel doors.

Outside/recirculation door is controlled by a vacuum valve and vacuum motor. When function control lever is in the OFF position, vacuum is applied to outside/recirculation door vacuum motor to close off outside airflow. When function control lever is in any other position, vacuum is not applied to outside/recirculation door vacuum motor and outside air is allowed to enter the vehicle.
