So my uncle put a fuse in my truck for the map lights and they started to work but i cannot figure out what fuse is for the dome lights, any help? Thank you!

 

You can download an owners manual from www.motorcraftservice.com. Go to the owners manual section. It is free and you can find the fuse number in it. I would suspect something else would not be working as they would not have a fuse for just the dome lights.

 

Might be the same fuse for the dome & map lights so maybe the bulb is just burned out.

 

Im gonna go with the bulb being blown.
