I'm insulating the Motovan. It's got additional dome lights built in. The rear door lamp was missing the cover, and it only worked when the rear door was open AND the other dome lights were on, either from another door being open our manual override. While insulating the rear door, I removed the light. None of my dome lights work now. I checked the fuse, called "illuminated entry module 5 amp" and that fuse was missing. Could not find any blown fuses. Put the rear door lamp back in the system and still no dice. No voltage at the rear door lamp wires either. It was just a red wire and the lamp was grounded to the door frame. Everything else is working. What next?
