interior light cargo light stopped working

[drewmgd73]

Hello all I have a issue that has me totally stumped. My interior lights n cargo light stopped working, but the map lights work. This is everything I have checked fuses all good relay good bulb good third brake light good and cargo bulbs good. What I did try was at relay 1 I took a wire and wrapped it around the prong of the relay and touched it to a fuse and bing go it worked but then the lights would not shut off. So im stumped can someone help me with this.i was told to check the GEM? Everything else inside works fine only the interior lights and cargo light. Also checked headlamp switch the dimmer switch works and with the lights on the chime works. Also sprayed wd40 in the locking device of the doors.
Thanks

UPDATE:
have change everything with dome light/cargo light and still nothing the dome light has power going to it and map lights work correctly but still no center dome light or cargo. If I touch the 2 power wires in the dome light housing it works but will not shut off so if anyone has any suggestions it would be greatly appreciated.
