My 85 Wagon Tailgate light is not turning on when I open the tailgate. Is this normal? (WTF). It does come on when I hit the switch on the main console. I can get it to turn on when the rear doors open "kind of silly". When I further tinker with it it seems to work "retarded". That is, the light turns ON "permanently" only when the tailgate is shut and it turns OFF when the tailgate is opened.

Any suggestions? Is there a contact on the rear tailgate or something that Im missing? Is the actual Dome LIght Assembly itself missing some kind of piece or mechanism aside from the "roller style switch"

THanks,
