Thanks for the reply, but I'm talking about the 4-position sliding switch for the dome/reading light, it's located right next to the dome light on my car.
The switch for the sliding sunroof is also up there, and it's illuminated, but not the dome/reading light switch.
I've got the dome light unit out, and all there is is a 5-prong plug that attaches to the rear of the sealed switch. I don't want to tear into the switch if there's no bulb in there -- looks like a lot of little pieces.
Anybody else know?
