I've got two switches. Wall mounted and riveted in place, indicating (to me, at least) they are original/factory installations. One is just inside the door (forward) and the other is on the same (curb) side, forward of the side window but not quite to the front windows.
I'm guessing one of them is for the outside light. This, however, despite a new bulb, does not work with either switch.
I'm sure I can eventually trace where each one should go and what it should be doing... but if anyone can shed a little light on this, it would help a lot. If I know what the switches should do, I can ensure the wiring is intact and fix the things.... grrrrr! This one is frustrating!
