Well I have replaced the rear tailgate of my 95 with a junkyard one, since it was crushed. I have everything operational except I can't get the rear defroster to work. When I press the button, the light on the defroster comes on, however the rear window does not heat up. It also does not defrost at all. So since the light is coming up, I think my fuse is ok but my wiring is messed up. Any help?
