I have a 1995 Ford F350 Mega Cab long bed. My head lights and turn signals all work and my dome light does to but when i go to put my marker lights and the running lights on they wont come on along with the lights in the dash. then when i put a fuse it and go to put the lights on it pops right away.but when i break and use the turn signals they work but just wont glow. so i dont know where to check.:dunno:
