Auxiliary Climate Control: Overview

An auxiliary climate control system is available as optional equipment. The auxiliary climate control system operation is determined by the settings on the front or rear auxiliary climate control assembly. The auxiliary climate control assemblies include a blower motor switch and temperature control/air distribution mode knob can only be serviced as an assembly.

Auxiliary blower motor operation is enabled when the HVAC system is in any mode except OFF. The auxiliary climate control system air can only be cooled below interior air temperature when A/C compressor operation has been requested by the settings of the climate control assembly of the base (front) system. The auxiliary climate control system air can be heated at any time.

The auxiliary climate control housing is located on the LH 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.

All of the auxiliary climate control system components are serviceable from the inside of the vehicle except the lines.
