Control Assembly: Description and Operation

Fig.5 Heater-A/C Controls:

The standard heater-only or optional heater-A/C control panel is located to the right of the instrument cluster on the instrument panel. The heater-only control panel contains three rotary-type control knobs, while the heater-A/C control panel contains four. There are separate control knobs for the blower switch, the mode control switch, temperature control and, on the heater-A/C models, an air flow control knob.

The heater-only or heater-A/C control panel cannot be repaired. If faulty or damaged, the entire unit must be replaced. The control knobs and the illumination lamps are available for service replacement.

Refer to Instrument Panel Systems for the heater only or heater-A/C control panel and control knob service procedures.

Both the heater-only and heater-A/C systems use a combination of electrical, cable and, on heater-A/C equipped models, vacuum controls. These controls provide the vehicle operator with a number of setting options to help control the climate and comfort within the vehicle. Refer to the owner's manual in the vehicle glove box for more information on the features, use, and suggested operation of these controls.
