Auxiliary Climate Control

AUXILIARY CLIMATE CONTROL

An optional auxiliary climate control system is available. The system is a one-piece unit that is located on the RH side of the vehicle between the side windows and the floorpan, behind the rear wheel well. The driver has primary control of the auxiliary climate control system or can transfer control to a rear passenger control panel.

Sytem Airflow:

The auxiliary air conditioning (A/C) and heating system has the following features:
- The auxiliary climate control system is functional whenever the instrument panel mounted climate control assembly is in any mode except OFF.
- The auxiliary blower motor recirculates the air inside the vehicle. Outside air is not available to the auxiliary system.
- Air is cooled and dehumidified by the auxiliary A/C evaporator core only if the front (main) climate control system is operating in a mode that requires A/C compressor operation.
- The temperature blend door and the auxiliary mode door are controlled by electric actuator motors.
- Movement of the auxiliary temperature control between cool and warm causes a corresponding movement of the temperature blend door to mix air flowing through and around the auxiliary heater core.
- Movement of the auxiliary mode control between PANEL and FLOOR causes a corresponding movement of the auxiliary mode door to direct airflow between the panel (headliner) registers and the floor duct.
