So I opened this up to see about putting a fan in but it really looks odd to me. On the left are three black wires connected together. In the middle two white wires with the white of the light and then a white wire is connected to the black of the light. The light had been working fine but one of my bathroom lights had been acting weird ever since we moved in. It basically stays on at all times whether the switch is in on position or off. If the bedroom wiring is incorrect how should I fix it?
