A/C Heater Control: Description

WARNING: This page is about a different car, the 2005 Jeep Liberty. However, it is still accessible from the selected car via links, so may be relevant.

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

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

a push button rear window defogger on/off control. The defogger button contains an LED that illuminates when the rear window defogger system is in operation.
a rotary control knob for fan speed selection.
a rotary control knob for recirculation and mode control of the discharged air.
a rotary control knob for temperature control of the discharged air and turning the heating-A/C system off.

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