I have a 1995 Nissan Pathfinder, and when I open the doors, only the middle cabin light comes on. There is one in the back, by the cargo area, but it never comes on. There is a setting on the light back that that looks like it would come on when the doors are open, but it doesn't. It does come on when I switch it on manually. Is that light suppose to come on when the doors open up with the other light?
