HEATER AND AIR CONDITIONER CONTROLS
Both the heater and heater-A/C systems use a combination of mechanical, electrical, and 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 for more information on the suggested operation and use of these controls.

The heater-only or heater-A/C control panel is located to the right of the instrument cluster on the instrument panel. The control panel contains a rotating-type temperature control knob, a rotating-type mode control switch knob, a rotating-type blower motor switch knob, and the Message Center. For more information on the Message Center.

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 Message Center bulbs are available for service replacement.
