When I turn the headlights or daytime lights on the instrument panel won't turn on and the reverse lights don't work. I checked all the bulbs and they are fine. The lights that illuminate the speed and tach gauges are the ones in the instument panel that don't work. It is also interesting that the sport light in the automatic tranmission turns off when I turn the headlights or daytime lights on. Any one know what the problem is?
