If you got the truck used, you might want to check for trailer connectors that have been spliced into the harness. I get one in like that now and then where somebody with a fifth wheel has cut and spliced into the harness over the axle and used wire nuts, rather than use the modular connector. The wires sometimes corrode inside the wire nuts and lose contact. Just a thought, cause those can be a real head scratcher and hard to find sometimes. If not, start at the multifunction switch harness and check for power there. ALSO check your fuses, #1 and 23 i believe.

Edit: The left turn wire at the multifunction switch harness connector should be> lt grn/org: right>org/lt blu
