The whole heating panel gets no leds and no blower if you turn the car off and on again. If you let the car sit off for 10 minutes to half an hour it works fine. Until you turn the ignition off. Then same problem. It doesnt matter if you run it for 30 seconds or an hour. It will work fine once its working. But its dead if you turn the car off and back on again with out letting it sit long enough. The led on the rear defroster is also out but it seems to work anyway. Not sure if that is related.
