Auxiliary Climate Control

AUXILIARY CLIMATE CONTROL

An optional auxiliary air conditioning and heating system is available. The auxiliary climate control housing is located on the LH side of the vehicle behind the rear wheel well.

Air Distribution
Vehicles with trim have a vertical duct that supplies air to the integral headliner air conditioning duct. Air is supplied to the passengers through six adjustable registers. The floor duct is integral to the side trim panel and has 4 fixed registers. The trim panel connects directly to the auxiliary A/C-heater unit.

Vehicles without trim do not have overhead registers or floor ducts. A unique register is used to distribute air-conditioned air and a heater outlet duct assembly distributes heated air.

System Airflow
The function selector switch (located in the front A/C control) controls the air distribution for both the front and auxiliary systems.
- The mode door is driven by a vacuum control motor to its predetermined position.
- When the function selector switch is in the FLOOR or MIX position, the auxiliary system will direct air to the floor.
- When the function selector switch is in the VENT position, the auxiliary system will direct air to the overhead vents.
- When the function selector switch is in the NORM A/C or MAX A/C position, air-conditioned air is distributed through the overhead registers.
- The auxiliary system uses only recirculated air from the vehicle interior.
