I bought my first f body yesterday and all seemed fine until the dash lights fog lights and break lights cut out on my way home. I've checked all the fuses none are blown. Further investigating revealed my tail lamp fuse in the dash isn't getting power. So I crossed a wire from a fuse that is and the lights and breaks work. This is fine for now but I dnt wanna leave it like that. Does anyone know of another fuses in the wiring that may have blown and if so where do I look for it. Its a 2000 ws6. Any help would be appreciated.
