When equipped with the rear A/C system, the controls for the A/C system are located in the front A/C-heater control in the center of the instrument panel. The controls for the rear A/C system are:
a push button for manually increasing fan speed.
a rotary control knob for rear temperature control.
a push button for manually decreasing fan speed and turning the rear A/C system off.
indicator lamps which illuminate to reflect when the rear A/C system is on and the selected fan speed.
a push button air recirculation control. An indicator lamp illuminates when the button is pressed.
The rear A/C controls are diagnosed using a scan tool.
The rear A/C controls cannot be repaired and the front A/C-heater control must be replaced as an assembly if inoperative or damaged.
