Thanks for your advice. I made the changes and the light switches on and off now!
However the fan will not turn off now. Well it did for 10 mins. But now it won't turn on at all now, my dodgy wiring skills perhaps?
At least the light works!
This what I did:
Hello. I have just moved into my house and cannot turn the bathroom light off. The previous owners did have a chandelier light fitted that they removed. I think they may have wired it up incorrectly when they fitted the pendant.
The switch also controls an extractor fan which works fine...
