Control Assembly: Description and Operation
Rear
DESCRIPTION
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.
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 See: Powertrain Management/Computers and Control Systems/Testing and
Inspection/Diagnostic Trouble Code Tests and Associated Procedures.
The rear A/C-heater control cannot be repaired and must be replaced if inoperative or damaged. The illumination lamp (4) and the control knobs are
available for service replacement.
