Manual Temperature Control (MTC)
WARNING: This page is about a different car, the 2017 Jeep Cherokee. However, it is still accessible from the selected car via links, so may be relevant.
The A/C heater control for the Manual Temperature Control (MTC) heating and A/C system allows one temperature setting for the entire vehicle. The MTC heating and A/C system uses electronically operated controls to provide the vehicle operator with a number of setting options to help control the climate and comfort within the vehicle. All controls are identified by International Standards Organization (ISO) graphic symbols.
The MTC A/C heater control is located in center of the instrument panel.
The A/C heater control cannot be adjusted or repaired and must be replaced if inoperative or damaged.
