Re: Interior dome lights have stopped working
Finding the offending wire, socket, or switch is going to be by process of elimination. I'd begin by turning off all things that have switches - the master on the dash, the luggage compartment light, and close all the doors. Have someone inside and a window open. With everything off, try inserting a fuse. If the fuse survives (take it out and look at it), try turning on a single light at a time inside the van. Front push button lights, the ceiling reading lights, the luggage compartment light. If one of those blows the fuse, you at least have a place to start. If all is still quiet, and with the dash switch off, try opening a front door. Try opening a side door, then the rear liftgate. Still good? Try turning the front dash switch to on. The idea is that something will suddenly blow the fuse, giving you a starting point.
Other approach is to pull open all fixtures and look for obvious damage and possibly a burn mark.
