Mercury Repair Questions? Ask a Mechanic for Answers ASAP
Welcome, I'm Chris (aka Moose) I'm an independent contractor here at Just Answer.
The first test from Ford is to unplug the headlight switch, can you do that and let me know the results?
Thanks for asking your question and letting me try to help you.
Based on your response the diag can go one way or another. I have to know the answer to step one prior to knowing what step 2 is. I read you can shut the lights off with the battery disconnected, though that is not a diagnostic step needed to figure this out.
Sorry you feel my assistance is a scam.
