You could try to rebuild the switch. That´s what I did. It was pretty easy. Mine is a 93 though. It would blow the fuse every time I turned it on. I took it apart and just cleaned out all the soot, and now it is perfect again. There is a little spring that alternates between holning the button in and not holding it in. It might have fallen loose. If any part is broken in there, though, you probably can´t fix it.
