My 03 Imp just rolled 200k! And then the AC stopped. Refrigerant is full and at good pressure. Blower runs. Warm air comes out. HVAC control lights are stuck, as well...AC and Rear Defrost won't light up, but Exterior and Interior air are constantly lit. Mashing of any of the buttons changes nothing. Air direction control works fine, as does the blower speed. Also, unsure if related or not, but the DIC won't automatically turn on any longer...it will turn on if I press and hold the center Home button. Can't find any blown fuses. Any ideas? It's raining and humid and this sucks! Razz

It does, and, occasionally, I actually get AC and the AC light is on, although all the buttons are still unresponsive. Could the climate control unit just be fried?
