Hey Javypro, if your dome light is acting up or not working correctly, it may need the contact rivets tightened. Mine didn't work at all when I got the truck but there was power there. I was able to remove the screws, wiggle the housing down, then use a pair of channel locks to squeeze the rivets (not the switch contacts) until the light turned on. Then I gave them all one last pinch and it's been working ever since. I guess the plastic shrinks or something. These go through the housing and one side are metal bars and the other are where the wires connect.
