Like the title says my dome light will not work, it doesn't matter which door is open, what position the key is in or whether or not dome override is pressed. Obviously I've changed the bulb, checked all the fuses, and the strangest part is I've checked it with a test light and there is power there. I've even taken a whole (working) assembly from another identical truck and that one didn't even work. The two lights on either side of the dome light DO work when pressed, and the lights under the dash come on. I'm completely out of ideas.
