I replaced the switch hoping to fix these lights flashing on and off again periodically. The gauges still go down to 0 and come back up right away and the lights flash. When the radio is off you can almost hear a "tink" sound, like a switch flipping. And today the whole truck shut off while i was coming to a stop. It did not sputter or shake/stall--just nothing. It started right back up w/no problems the rest of the way. Any ideas???
