I bought a thing that hooks up to my car's cigarette lighter, to make the car smell better. When I put it in it sparked and blew out the light above my head, and then I realized my radio and horn don't work anymore either. I could care less about the horn, but not having a radio is killing me. The clock on it still works, but the radio wont come one. I don't think it is the fuse, I was just wondering what else it could be. I have 1989 Chevy Caprice btw.
