Well, I kind of found the short. It is in the left sun visor somewhere. I currently have it removed from my car and all of the lights work fine. I was not able to locate the short in the visor, so I am getting a used one from a junked W126 for about $50. It is hard to find the black visors in good condition, though. Thanks for the help everybody.
