Recirculation Mode

When the RECIRCULATION switch is pressed, a solenoid inside the HVAC control assembly connects the recirculation vacuum actuator to the vacuum source. Power is provided to the recirculation switch by the ignition 3 voltage circuit. Ground is provided by the ground circuit. The recirculation actuator retracts, closing the recirculation door. This brings air from inside the vehicle instead of fresh air from the outside.

Recirculation is available in all modes except FRONT DEFROST and MIX-BLEND. The recirculation mode will stay on and the LED will illuminate until either outside air is selected or the next ignition cycle. Recirculation can be selected with the blower motor in either the ON or OFF position.
