My cleaning method seems to have worked on the dome/map light. Works perfectly when I open the passenger door, and often when I open the driver's side door. I will have to look at that door switch later... Anyway, the light that comes on when you open the hatch has an issue with it's ground wire. I can wiggle the wiring that goes between the body of the car and the hatch and the light comes on. I pulled back the wiring cover that goes to the hatch and yeah I see two broken wires and at least one more missing the insulation!
