ok my step sons POS Jimmy has some electrical issues. if he first starts the truck in the morning, the brake lights, turn signals, and back up lights all work. after it has run 5 minutes they stop working. it almost seems like once the truck warms up, the lights **** up with it. if he just applies the brakes, just the brake lights come on. if he puts the turn signal on and hit the brake, the tail lights and back up lights flash and alternate like a cop cars.
