I just bought a house that has a light switch that controls nothing! How
do I trace what this switch is supposed to do without ripping out walls to

Remember the Steven Wright joke:

"In my house there's this light switch that doesn't do anything. Every
so often I would flick it on and off just to check. Yesterday, I got a
call from a woman in Germany. She said, 'Cut it out.'"
