Here we go again!! okay I know it's not the fuse or door switch, I've tracked it down to the Dome light assembly, there's something going on with the 3 screw deal, My cousin was working on it, when he left one of the screws out the light would come on with one of the map lights,not by itself though, however the cargo light never came on...so in other words, I still don't have a clue.
