No power to TREC Fuse
Hi everyone, I have a 2003 Yukon XL 5.3 4wd. From what I can tell I have a pretty unique issue. When I bought it someone had jumpered a wire from the prime port (aux power for testing) to one leg of the TREC fuse so the 4wd would work. I figured this out when I tried to put it in 4wd and it...- WestLinnYukon
