Its a Cheyenne with sealed beam headlights. Not the quad type. My hi beams aren't working and I've been trying to diagnose. The 3 wires at the headlight are light green, tan and black. I get no power to the lt green when switching the headlight dimmer switch to HI and no bright/hi beam indicator in dash.
When I took the headlight dimmer switch off and looking for a lt green to test and I don't see a lt green. I probed all the wires for one that turns on when I switch to HI beam on dimmer and found that its a white wire that turns on when I switch hi beams on. This differs from the manual. Do I just need to trace this wire and find where its broke?
