Sounds a bit odd, but from what I have read it sounds like the dome light switch might have a few connections to it for power. Sounds like the o'l Hazard light switch trick, when your turn signels go out and the fuse isn't to blame, flip the hazard switch a few times and it usually fixes it. If i'm right, at all, i would just replace the dome light switch, there could be some bad contacts on the switch. Anyone have any other input on this. btw, ebay usually has these switchs up for sale for about $5.
