I just changed the 4x4 transfer case module on my 2002 Ford Explorer but now…
Okay, so, my back running lights for night will only come on when the lighting switch is turned to the auto position. However, when I have the switch in the auto position my dash back light will not work, that only works when the switch is in the on position. So, I really have an issue at night ha I can’t win either way! Advice on what the problem may be is really appreciated! I know enough to get by, but being a young female I still get some mechanics trying to rip me off. I would rather get someone else’s advice first!
Sounds like you may have a relay sticking. Here is a copy of the wiring diagram to help assist in your troubleshooting.2002-ford-explorer-exterior-lights-exterior-lamps-circuit-early-production-1-of-1
