Check the wires under the driver's door jab. Years of vibration, small rocks and such can wear through the wires and break them. Or create a short and blow the related fuse.

Yes. I had a dome light fail in a past vehicle and the cause was a hole in one of the wires under the plate.

Not sure on which fuse. One that is hot all the time.

Should have 12V. As kwmech mentioned, light is hot all the time and the door switches close to ground when the door opens.

Needs to be battery voltage at the light 12v +.. you have a broken wire or fuse out. Trace it from the fuse block. Should be an orange wire coming from the fuse block and going underneath the floor mat

That sounds like the color code for factory speaker wiring. Yellow & brown for left rear. Over on the other side you'll likely find light & dark blue wires for the right rear speaker.
