Air Distribution and Filtering (Air Distribution)

AIR DISTRIBUTION AND FILTERING

NOTE: The air distribution system of this vehicle is factory equipped with a cabin air filter.

There are two sources of air available for both the electronic automatic temperature control (EATC) and the manual climate control air distribution systems:
- outside air
- recirculated air

Electronic Automatic Temperature Control (EATC) Air Distribution
Recirculated air is automatically used during OFF mode. Recirculated air is also available in any mode except DEFROST or FLOOR/DEFROST by selecting the RECIRC function. Air inlet will automatically be determined by the remote climate control module in the AUTOMATIC mode.

Air distribution within the vehicle is controlled by the electronic automatic temperature control system in the AUTOMATIC mode, but it can be overridden by the driver if desired. Airflow mode doors are used to direct airflow within the A/C evaporator housing and plenum chamber. Vacuum control motors are used to position these airflow mode doors.

The air distribution system is designed to provide airflow from the defrost nozzle when no vacuum is applied to any of the vacuum control motors. This is done to prevent a situation where defrost cannot be obtained due to a system vacuum leak.

Air enters the passenger compartment from the:
- instrument panel A/C registers.
- heater outlet floor duct.
- windshield defroster hose nozzle.
- side window demisters.
- rear seat airflow duct.

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

Manual Climate Control Air Distribution
Recirculated air is only used during MAX A/C and OFF modes.

Air distribution within the vehicle is controlled by the position of the function selector switch. Airflow mode doors are used to direct airflow within the A/C evaporator housing and plenum chamber. Vacuum control motors are used to position these airflow control doors.

The air distribution system is designed to provide airflow from the defrost nozzle when no vacuum is applied to any of the vacuum control motors. This is done to prevent a situation where defrost cannot be obtained due to a system vacuum leak.
