Control Assembly: Description and Operation

Both the heater-only and heater-A/C systems use a combination of, electrical, cable, 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.

The A/C-heater control for the heater-only or the heater-A/C system is located to the right of the instrument cluster in the instrument panel. The A/Cheater control contains rotary-type knobs. There is a blower motor speed switch, mode control switch, temperature control, and airflow control.

The A/C-heater control cannot be repaired and, if faulty or damaged, it must be replaced. The control knobs and the illumination lamps are available for service replacement.
