Air Distribution and Filtering

AIR DISTRIBUTION AND FILTERING

NOTE: The air distribution system of this vehicle cannot be equipped with a cabin air filter.

There are 2 sources of air available to the air distribution system:
- outside air
- recirculated air

Recirculated air is only available when the electronic manual temperature control mode selector is set in the MAX A/C or OFF modes. Recirculated air is available in all modes except DEFROST. If the vehicle is equipped with an electronic automatic temperature control (EATC) system, recirculated air is used in OFF and is available in all modes except DEFROST.

Air distribution within the vehicle is determined by the electronic manual temperature control (EMTC) function selector switch position, or is controlled by the electronic automatic temperature control (EATC) system in the AUTOMATIC mode. The air distribution mode on electronic automatic temperature control (EATC) vehicles may be overridden by the driver if desired. Three independently actuated air distribution doors are used to direct airflow within the heater core and evaporator core housing and the plenum chamber. Electronic mode door actuators are used to position these air distribution doors.

Air enters the passenger compartment from the:
- instrument panel A/C registers.
- heater outlet floor ducts.
- windshield defroster duct.
- side window demisters.
- center flow-through console (if equipped).

Passenger compartment air is exhausted from the vehicle through open windows or body air vents.
