MANUAL TEMPERATURE CONTROL (MTC)

The A/C-heater control (1) for the manual temperature control (MTC) single zone front heating-A/C system allows the front seat passengers the ability to manually regulate air temperature, fan speed and output modes. All controls are identified by ISO graphic symbols.





The front MTC A/C-heater control (1) is located in the instrument panel and contains:

- a rotary control to select comfort temperatures (2).
- a thumb wheel control for manually increasing/decreasing fan speed and turning the system completely off (3).
- a push button air recirculation control (4). An indicator lamp illuminates when the button is pressed.
- a rotary control for manually selecting output modes (5).
- a spring loaded note paper holder (6).





The MTC A/C-heater control (1) is mechanically connected to the blend-air door and the mode door cam by use of flexible cables (2 and 3).

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