Is it possible that it's a fuse? Not that I expect a fuse to control that many things, but it's worth a check just to make sure. I had a car where I installed the stereo wrong, and it would short out all the interior lights. Aother car had the cigarette lighter and horn on the same fuse. Weird combinations, you never know.
