Evaporator Temperature Sensor / Switch: Description and Operation
Temperature Control
Rear A/C Temperature Control
The optional rear heater-A/C unit output temperature is controlled by a thumbwheel-type control, mounted in the switch panel on the instrument panel.
The temperature control allows the selection of four temperature settings when the A/C switch on the front A/C-heater control and 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.
