This is the page from the manual that covers the headlight switch operation.I have the dome light working when the doors are open and then it goes off when the doors closed. I am not sure if the light is supposed to come on when the headlight switch is turned all the way to the left or not
Sure is. You can see here the tab that gets grounded when you rotate the switch all the way to the left. One pic shows it open and the other closed. Your tab might be broken off.Is it possible that only that part of the switch is bad. the headlights work, the dimmer works but no interior light
Good for you as you found the problem, but I believe, and others will correct me if I'm wrong, but fully clockwise past the detent turns on the dome light and clockwise in general increases dash light brilliance.After reinstalling into the dash, the dome light worked when turned all the way to the left since I now had a ground.
