A/C - HEATER CONTROL

DESCRIPTION

A/C-Heater Control - Typical:




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.

The A/C-heater control is located in the instrument panel and contains:
- a rotary control knob for blower 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 blower motor and mode control switch, control knobs and illumination lamps are available for service replacement.
