Headlights on but no parking, interior, license plates, and tail lights

Asked by Sep 15, 2017 at 09:22 PM about the 1994 Lincoln Mark VIII 2 Dr STD Coupe

Question type: Maintenance & Repair

I have a 1994 Lincoln mark 8 2 door 4.6l car. The issue I'm
having is that my parking lights, interior lights, tail lights,
or license plate lights, do no illuminate when the
headlights are on. What would be a cause for this? This is
a recurring problem and in the past, replacing the
headlight switch would do the trick, but today I replaced
the switch and am still having the same issue.

1 Answer


then I'd say thats where the problem lies , check the wiring associated with the switch , something may be loose, a junction that powers those circuits , , a multi tester would help
