My friend bought a 2003 F-150 super-crew and after 4 month the dome light fuse blew. He took it back to the dealer and the tested the vehicle and found no problems with the electrical system. What they did to rectify the problem was" put a new fuse in it and said try this and come back if the fuse blows again. " well the fuse blew again and is at the dealer again.
