When I was drivin down the expressway with my headlights on at night I hit a bump and then heard a pop. All of my dash lights and the gear indicator (PRND32) lights went out. When I home i checked and saw the blown fuse. As soon as I put in another one and turned the lights on it popped again. Im gonna go ahead and geuss it's a short, but how likley is it that the dimmer switch is causing this? Any tips on locating a short? Or even a wiring diagram would help. Thanks
