The dome lights in my "new" 99 F250 have two switch positions. I'm assuming Off and Door. I'm also assuming I should be able to turn them On by using the dimmer switch on the dash. If I set the dome lights to Door, they will stay lit even when the doors are closed. I've already tried to spray WD-40 in the door latches, but that didn't help.Panther Black, AWD, 6 Speed Auto, 1.6lt ecoBoost Turbo Petrol.

Unplugged the BEM and plugged it back in and its fixed.
The lights will dim and go off if you turn the ignition to II with all doors shut - does it do this? If you can test both 12V supplies whilst you do this it may help. You can also see if there is a door sensor fault, turn your ignition off and take your keys out.
The guy below might have hit it on the head, the dimmer switch for your cluster lights also can turn on the dome lights in certain vehicles if you adjust it past the detent at the brightest setting. Try that and see if it does anything. DefinitelyCaligula • 8 yr. ago.
I remember seeing this question before for the same reason, a drive in. AFAIK, you can't turn them off. In my 2014, I have to turn off the lights that come on when the doors open to make sure the interior lights turn off. The small lights in the trunk usually stay in though. I have a 2016 and if you leave the trunk open they time out and turne6far.
