I searched this forum for a topic relating to this, and didn't see it. If Im too blind to see today I apologize.
But this is something I encountered on my 2004 Overland, and apparently it's not that uncommon:
One time when I went to take off, I noticed the dome light would not shut off. Period. While trying to figure that out, I also found that my drivers front window wouldn't work either. Well as it turns out, the ground wire that goes from the window motor to ground that passes through the rubber wire guard between the door and the body was broken right in the middle of the wire guard. The factory ground wire is too stiff and is subject to breakage. This apparently will cause backfeed through the dome light assembly.
What I did is run a heavy speaker wire (and I mean a nice heavy one) in the original ground wire's place. Much more flexible, but is meaty enough to provide a solid ground. Problem solved-lights go out and window works.
