DESCRIPTION






NOTE: Typical A/C-heater control shown.

The A/C-heater control (1) for the manual temperature control (MTC) single zone system allows one temperature setting for the entire vehicle. All controls are identified by ISO graphic symbols.

The heating-A/C system uses a combination of electrical and cable operated 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 is located in the instrument panel and contains:

- a rotary control for mode control of the discharged air (2).
- a rotary control for blower motor speed selection and to turn the blower motor off (3).
- a rotary control for temperature control of the discharged air (4).
- a push-button control to turn the rear window defogger system on and off (5).
- a push-button control for recirculation control of the discharged air (6).
- a push-button control to turn the A/C system on and off (7).

The A/C-heater control cannot be repaired or adjusted and it must be replaced if found inoperative or damaged. The control knobs for the A/C-heater control are available for service replacement.
