Overhead Computer quit

The other day my overhead computer (the whoha that tell miles per gallon, avg miles per gallon..etc).

I've also noticed that my trailer lights quit working too. The wiring for the trailer was installed by the previous owner. today i went and traced the power wire and came to a control box (wires are not burned and seem in good shape). the trailer wiring was installed by U-Haul. the power wire for the trailer lights has an inline 10 amp fuse and is not blown. The only fuse box I know is the one under the hood, but looked at the diagram and cannot find any fuses for the overhead computer.

Can some one tell hat fuse that's on, or any other advice of where to.

There may be another fuse box behind the right hand kick panel in the footwell. Maybe you'll see a blown fuse there. Not sure where/how U-haul would wire this.

No, but is there anything else not working? Everything in the overhead console still work? Lighter and power ports working? The computer has to be on a circuit with something else. Check the fuse box under the hood, my computer didn't work when I picked up the car a couple of months ago. Bad fuse in the fuse box under the hood. Don't remember the #, but look at the info on the panel and it will show.
Did the computer quit completely or just the bulb burn out making it hard to see?
