Air Distribution and Filtering

AIR DISTRIBUTION AND FILTERING

NOTE: This vehicle is not equipped from the factory with a cabin air filter.

There are 2 sources of air available to the air distribution system:
- Outside air
- Recirculated air

Recirculated air is always used when the climate control assembly is set to the MAX A/C mode on vehicles equipped with manual climate control. Vehicles equipped with electronic automatic temperature control (EATC) use recirculated air only when the RECIRC function is selected in any mode other than DEFROST, or when required by the EATC module in the AUTOMATIC mode.

Air distribution within the vehicle is determined by the function selector position (manual A/C), or the EATC system in the AUTOMATIC mode. The air distribution mode on vehicles equipped with EATC can be overridden by the driver if desired. Airflow mode control doors are used to direct airflow within the heater core and evaporator core housing. Electric mode door actuators are used to position these airflow mode doors.

Vehicles equipped with dual-zone EATC use 2 separate temperature blend doors. This allows individual temperature settings to be selected for the RH and LH air outlets. The airflow mode doors are not partitioned for separate RH and LH airflow positions. Therefore, the airflow mode will always remain similar for the RH and LH sides of the vehicle regardless of the temperatures selected.

Air enters the passenger compartment from the:
- instrument panel registers.
- floor duct.
- windshield defroster.
- side window demisters.
- rear footwell duct (if equipped).

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