Once in a while, the illumination for my fuel and coolant temp gauges goes out
I picked up some extra bulbs at the junkyard, but the lights mysteriously started working again last night on their own. I also have a tail light that goes on and off when it feels like it, and my left turn signals blink faster than the right ones even though there are no bulbs out. I know the electrical system is not the strong point on these trucks. Any suggestions on where to check for loose connections, or should I just hire an exorcist?
