1985 j60, First my reverse lights went out then I started blowing the wiper fuses. At first they blew now and then after a few month's ( not my daily driver) the fuse would blow as soon as I started the truck. I have checked the wiper relay and it's good. I have unplugged the reverse light switch and the wiper motor and it still blows. I can't seem to find a short anywhere but it seems to be a dead short as soon as I turn on the ignition. Any help would be greatly appreciated. I'm leaving for Colorado in 36 hours and it would be really nice to have wipers.
