Interior lighting

HI all, I have a 2013 jsw in which the dome lights and footwell lights have never worked besides the cargo area light which only comes on only when the rear hatch is open. I have checked all the fuses for continuity and visually inspected the map light switch assembly.

The code from obdeleven is, Terminal 30 for interior illumination, Open circuit. Footwell Lights, Open circuit/short circuit to B+.

Any help or even a wiring diagram would be much appreciated. Thanks
