They get sourced by ground door switches on a yellow wire. This wire must be plugged on some provision around on underdash harness
Correct and the pink wire goes to the back of the fuse box. Remove the three screws and pull the light down. The yellow wire should be plugged into the top post of the housing see if it popped off. The switch either grounds through the housing which it is doing. or the yellow wire door switches, which it is not. The pigtail from the light goes down to the main harness and that should be plugged into the yellow wire off the main harness, see if that came apart there as well.
