Its a light blue 15 amp fuse, located in the fuse box (obviously) Its the same fuse that goes with the the radio, so if you blew it your radio shouldn't work either. At least thats how it works on my 1990.
Yeah its the fuse thing under the dash, by the pedals. The fuse you are looking for is a light blue fuse near the top right of the box. It should say radio above it.
