I don't know the exact name, but my lariat has a compass/temp digital gauge on the ceiling. Which one is it? It doesn't light up anymore. Is this a fuse?

 

That would certainly be the first and easiest thing to check. It's what I'd look at first. If it's not a fuse and it's digital, you may have a fault in the circuit board, such as a bad solder joint, or a failed component.

Sorry though, I don't know enough about the device in your truck to be more helpful.
