Issue with Lights

Hi everyone,

I have a 2000 Coachman Santara Class A. I'm having an issue with the lights on the motorhome. When I turn on the headlights, everything is working, headlights, taillights, and running lights. After a minute or so all the lights except for the headlights go out, including the dash lights. Anyone have any ideas on what the problem might be or where to start troubleshooting? Thanks!

  • Thanks for the replies. Is the switch your talking about the one to turn on the lights, or is it another switch you are talking about? Thanks

    The OEM headlight switch is overloading and the integral circuit breaker is tripping. Unbelievable. Ford had this issue 38 years ago and never fixed it.

    Either patch it up with a new headlight switch replacement

    Or add a relay to power the small BROWN wire the exits the cab and powers tail and clearance lamps.

    Really, Ford had a supposed issue 38 years ago and you state it must still be an issue????? There are tens of millions of these Ford switches out there. IF there was a supposed defect, don't you think there would be a great outcry on this supposed problem? The simple fact is, the OP has a 18 year old Headlight switch that has failed from 18 years of current flow. Just replace it, NO BIG DEAL. Doug
