Temperature Control

Rear A/C Temperature Control:

The temperature control for the optional rear A/C system is a thumbwheel-type control mounted in the switch panel on the instrument panel. The rear A/C temperature control allows the selection of four temperature settings when the rear A/C blower motor is activated.

With the front A/C switch and rear blower motor activated, the rear A/C output temperature can be selected by rotating the thumbwheel control upwards (increase cooling) or downwards (decrease cooling). Depending on the rear A/C temperature control position, a temperature command signal is sent to the rear A/C control module. The temperature of the circulated internal air of the rear compartment is measured by a temperature sensor located in the rear evaporator unit. The value of the temperature sensor is compared in the rear A/C control module with an adjusted value at the rear A/C temperature control.

The rear A/C temperature control cannot be repaired and, if faulty or damaged, it must be replaced.
