2004 Ford F-150 dome lights will not shut off

It could be a bad contact on the slider door,(or any of the doors) but they were known for the slider door contact.

possible solution is your door switch is faulty or grounding out. could also be the headlight switch. both of those parts you can get at almost any salvage yard

For the none rail system front console ( where the map lights are at ), open the rear compartment, and grab each rear corner, and pull down hard.
It is held up with 4 ( 6? ) spring clips. It will be very hard the first time you do this.

If you are talking about the rear dome lamp, if you checked the 3 position switch location ( on, on w/ doors, always off ) if you look at the side opposite the switch, you should see a notch in the lens, this is where you use a small screw driver to carefully push in the tab that holds the dome lamp up.

If it is the rail system, the front is still held on with spring clips, and is a bit tricky to get a good hold. I suggest a plastic trim tool to grab the end of the console where it meets the roof liner, to pull it down.
