I recently bought a 93' Jeep Wrangler, the previous owner had installed a new radio about 5 years ago but has never had problem with the dash lights. About 2 days after buying it all dash lights went out and the fuse blew. I replaced the dimmer switch and then the lights worked for a day. About 30 mins ago they went out again and the fuse blew. The Dome Light turns on when i turn the dimmer all the way up though. Does anyone know any ways to fix this?
