I know this is an old thread, but i thought I will let you know what I found with the dome lights. My dome light was out also. Since I do not have a warranty I unscrewed the 2 screws holding the light unit. I found that the medal traces are held down by some cheeeap plastic rivet things. I went to kragen and bought some metal, plastic epoxy. I epoxied the 2 traces that were broken and glued the other rivets. I am sure they would have broken eventually. I popped the whole unit back in. Perfect. Five min. Job.
