By hot weather, My aux fan starts by itself, even when the engine is turned off. Anyone knows why? I had to disconnect it to avoid draining the battery.
Also, when I disconnected the fan, the little plastic socket came apart and now I don't know which wire goes where. On the aux fan side, I have a blue/Black and a brown one, and on the other side, I have a black and a brown wire. Should the brown wires connect together?
