Concur that power to the two map lights comes from fuse 24.
Have you tested the bulbs?
Do the visor mirror lights work?
If fuse 24 and the bulbs are good , and the visor lights don't work, then I'd check the battery saver relay (#304 on fuse panel).
If you do the above and the lights still don't work, I'd inspect and test the wiring from fuse 24 to the lights.
Good luck.

If the visor lights work, F24 is okay. No need to mess with it or the battery saver relay further for the map light circuit.
Does the rear seat map and courtesy light work? Need status of both functions.

there’s only one light in the back I guess that’s the courtesy light and yes that works.

Finally... an actionable answer.
The problem is going to be localized to the front overhead light fixture. Open it up or pull it down and inspect both bulbs as well as the connections. Either both bulbs are blown or something is disconnected.
