It's a door ajar switch. The GEM runs your dome lights, not the BCM. The switch is grounded when the door is open, and the switch is open when the door is closed. Disconnect the harness with a P/LG and BK wire(remove the interior door panels and find the harness on the door latch). If the dome lights go out, thats your problem switch.

Pink/Light Green and Black
If you sprayed WD-40 on the latch and it started working, your door ajar switch is sticking. Replace it, the lube will fix it for a while but it will eventually stick agian.
