On my 2000 CLK430 (80K) I'm getting conflicting outside temperature readings. On the gauge cluster the outside temps are correct whereas the sensor readings at the climate control #2 sensor shows temps that are in the 110-140 range when the outside temps are in the 70's. I unplugged the sensor at the bumper and then the gauge cluster shows -36 so i know the sensor is working and that it reports to the gauge cluster. I should have checked the climate control readout but I didn't - so I have to redo that test. The climate control unit thinks it very hot so unless I jack the temps to HI/HI I will not get heat. Any thoughts? Is there another sensor for the climate control unit or do I have a wiring issue or god forbid is the climate control faulty?
