One of the two license plate lights are not working on my car. I have bought new bulbs switched them around and they both work in one but not the other socket. Any ideas? I doubt its a fuse because both would be out (I would think). I think its the housing its self. If so any ideas where to get a replacement and how to remove and install it? Has anyone else had this issue? I did have some work done on the car where they may have removed the rear bumper to paint it. Anyone know where to find a wiring diagram? Maybe its just a loose connection? I read online that other people have needed to replace the entire housing due to corrosion.
