I believe the way the fade works on the light is that it is just a capacitor that slowly discharges after you close the door. If it was shorted out maybe it would be your problem, but I doubt that would happen.
Which light is staying on? Driver door, passenger door, dome light, or all 3? Also, the door sensor should be along the inside frame and it's just a button you can manually press in to simulate a closed door. I'm betting your door just isn't lining up properly and can't fully latch all the way.
