Control-A/C-Heater

The rear A/C-heater control (1) for the rear heater-A/C system is located at the rear of the center floor console and allows intermediate seat passengers to adjust rear temperature and blower motor speed when the front A/C-heater control is set to the Rear position, otherwise the front A/C-heater control operates both the front and the rear heater-A/C systems. The rear A/C-heater control contains:
- a rotary control knob (2) for rear fan speed selection and turning the rear heater-A/C system off.
- a rotary control knob (3) for rear temperature control.

The rear A/C-heater control cannot be repaired and, if faulty or damaged, it must be replaced. The illumination lamp (4) and the control knobs are available for service replacement.

With the rear A/C-heater control active, temperature selection dictates the air distribution mode (floor or overhead air) of the rear heater-A/C system. A cool temperature setting directs flow to the overhead outlets and a warm temperature setting to the floor.

The rear A/C-heater control is diagnosed using a scan tool.
