2007 GMC Yukon
2007 GMC Yukon battery dead this morning. Jump started, headlights will not shut off. Cannot turn headlights off manually with switch. Checked relay, fuses-ok. Unplugged BCM, multifunction switch, headlight switch, headlights stay on. Going by the wiring diagram there is 1 wire that runs from low beam relay to BCM. I am thinking 2 options- bad wire or something bad inside fuse box. Anyone have any other ideas?
