As the dash switch works, and the lights light, my guess is that the problem is in the door switch--- although I haven't looked at mine, I assume that they are plungers that get pressed as the door is closed -- they should be located in front of the doors in the -"door well" (?)- put the dash-light switch in the "open door activate" position, open the driver side door and then press the plunger in and hold it, if the lights don't go out, try opening the passenger door (closing the driver door) and holding that plunger in -- I would assume if either plunger is bad (that is not working when presssed in) the lights would stay on. At least this way you might narrow the problem to these door switches.

This is the procedure I would use to eliminate the door plunger switches as the problem -- maybe we could hear from some tech. people on this?
