MANUAL SINGLE ZONE





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

The A/C-heater control and integral computer is located in the instrument panel and contains:

- a rotary control for fan speed selection and turning the heating-A/C system off (2).
- a rotary control for temperature control of the discharged air (3).
- a rotary control for recirculation and mode control of the discharged air (4).
- a push button A/C on/off control (5). An LED in the button illuminates when the A/C system is in operation.
- a push button rear window/side mirror defogger on/off control (6) when equipped with optional rear heated window and/or heated mirrors. An LED in the button illuminates when the rear window/mirror defogger (EBL) system is in operation.

The A/C-heater control for the MTC system is diagnosed using a scan tool Testing and Inspection.

The A/C-heater control cannot be adjusted or repaired and must be replaced if inoperative or damaged.
