Mode Selector Knob
WARNING: This page is about a different car, the 2001 Mazda Tribute. However, it is still accessible from the selected car via links, so may be relevant.
Mode selector switch combines a vacuum selector valve with 2 electrical switches to supply power to A/C clutch circuit and blower motor control circuit. Mode selector knob can be placed in MAX A/C, A/C, PANEL, OFF, PANEL & FLOOR, FLOOR, FLR & DEF (floor and defrost) and DEF (defrost) positions. MAX A/C and A/C positions control A/C compressor operation. PANEL, PANEL & FLOOR, FLOOR, FLR & DEF (floor and defrost) and DEF (defrost) positions direct airflow to chosen outlets. Defrost position activates A/C compressor to dehumidify air directed at windshield. Mode selector knob position determines which mode doors are open, partially open or closed. Mode doors direct airflow to selected outlets. See VACUUM DIAGRAMS .
