Interior lights will not turn off

Thanks 68,

I know my dash dimmer is iffy and I never liked how it functioned. As you dim the switch it will cut out the dash lights totally, then flicker and do its own thing. Perhaps I will look at picking up a new one of those. The door switches are very different than anything I have seen.

The drivers door has 3 wires going to it and it has a cone shaped contact area for the brass. The passenger door has 2 wires but also cone shaped. No terminals on the end of the wires and they look soldered onto the brass pins. They also have one large nut that screws into the door jam. Is this typical for these cars?
