Hey all, new here, and honestly am at my wits end.. I have an 05 express work van, about a month ago all the rear lights went out, brakes, tail lights, reverse, and turn signals. Had a blwn fuse, and the 2 3rd brake lights were burnt, replaced all of that it all worked again for about an hour. Now it constantly blows fuses, can't replace them fast enough. I've looked for shorts, checked the grounds. I'm at a loss, if anyone can help I'd really appreciate it.. Thanks all, Matt

 

you may have checked for shorts ie wires touching the frame or etc, did you check to see if the wire casings had melted togather and have a internal short inside the wire ? didnt GM have a 10yr/100k warrenty back then?
