The instrument lights on the dash of my truck stopped working. Whenever you try to turn them on. The fuel gauge zeros out and the right turn signal indicator on the dash comes on. I also get a little feedback coming through the high ram indicator. All the other lights and gauges still work properly including the turn signals and the lights for the accessory gauges that are hooked up to the same circuit. When the instrument lights are off everything is fine. It sounds to me like there's a bad ground. But I've checked everyone I can find with no improvement of the symptom. I've done the ground under the dash by the emergency brake lever. And the grounds at both turn signal lamps. I also disassembled the headlamp switch and saw no signs of burning corrosion or failure. Are there any other grounds I may be missing or missed? Or could it actually be the headlamp switch?
