Ok, my 93 940 does the same thing with a slight twist: the dome light sometimes times out just like it should, other times it won't go out, and still one other mode of quirkiness: light dims, dims some more and almost goes out then BINGO! Full Brightness. I gave up and just run the small lights (map lights I guess is the right term). I always wondered whether these lights run off some sort of solid state timer and perhaps mine is shot. Where do I find this timer, relay, (troublemaker) whatever, in the car?

Thanks
