Mode Air Valve

After passing through the evaporator core, all or part of the cooled and dehumidified air will pass through the heater core. The air will heat to the desired temperature that the driver requests.

The adjusted air enters the air distribution chamber. The heater and A/C programmer energizes the mode door actuators to position the valves in the air distribution chamber. Variations in the position of the mode valve door directs airflow through the floor, windshield and instrument panel ducts. Air is always directed to the rear air floor duct.
