    This morning when I started the truck, I turned the headlight o. And clearance light on also. Separate switches for both. They all came on. Went inside and 10 minutes later they where off. Fuse is not blown and the switch works because when I flip it it turns on the lights at the gauges . Any other place I should look?

    The switch is multi terminal using independent terminals for dash and clearance lamps so it could still be the switch or a ground issue.

    Hi Desert Ca
    There is also a bulkhead plug behind the glove box that feeds all the roof section I have seen terminals work loose there.do you have a fuse or a breaker petes have a problem with leaking winshields that allow water to damage the back of the fuse box.but I would start with benders advise and check the switch first
