Dome light issue

Sounds like the Socket is fouled up. Bulb not grounding or not making the positive connection through the socket.
I know its difficult to work overhead, If you had the dome light on a bench you can see or repair it with ease. Even test it with a 12v power source.

DOME LIGHTS DO NOT GROUND THROUGH THE SOCKET SHELL

The functional path is fuse---power to the dome light one bulb contact--through the bulb--out the other contact--to the "yellow wire" system which is the switched ground leg--and to the door switches and to the switch contact on the headlight switch When any switch in the yellow wire system is closed THAT is the ground for the bulb

Check power down at the fuse panel and make sure the supply wire is getting power.

This is the list of components supplied by the fuse

Dome lamp should be M1-18P (pink) coming off the fuse. This leads down to the kick panel connector for the rear harness so check that for power. Goes back behind the rear seat, up into the roof and to the dome lamp

The switched yellow comes back to the same connector, and branches off there to the headlight switch and the door switches
