Every other light in the car works. The back lights on the AC - Heater controls do not light. When I press the AC button, I can hear the compressor kick on but the light that indicates it is turn on does not light. When I select the rear defrost, I can a click in the back of the car, so I assume it is working but the light does not lite to indicate it is on. When I press the recirculate button neither of those lights work either. Otherwise everything works fine as far as the heater and AC is concerned. Any help would be appreciated.
