Function Selector Switch

The function selector switch can be placed in OFF, vent, floor, mix and defrost positions. The position of function selector switch determines whether function doors are open, partially open or closed. Function doors direct airflow to selected outlets. The 3 vacuum motors and doors are outside/recirculated air, defrost/panel and defrost/floor. See VACUUM DIAGRAMS .
