Back up light fuse.
My truck keeps blowing the reverse light fuse. I've checked all the wiring, and it's all good. I even disconnected my extra back-up lights, and it still blew the fuse. Never has done this before. The fuse is #27, and the owners manuel says that it also is used for the Electric shift,DRL's,Transmission control switch, and the vacuum hub lock. How do i check these other things mentioned? It blows the fuse as soon as the truck is put into reverse. HELP!
