So.. I'm not a big repair person, but I refuse to hire an electrician to something I can figure out.. I have a 3 way connector to the light switch in the kitchen.. I opened it up and tried jiggling around.. The thing that is annoying me is I'm certain it's the black wire that is the problem.. When I move it around try to angle it or push down on it in obscure angles, the light switch seems to work. I managed to somehow fix it before by pushing on the black wire and cramming it back into the wall, but now I can't seem to do that again. Is the connection loose or something? What can I try to do to fix it?
