I didn't pull a fuse, nothing happens when you turn on the wiper because you've removed the motor and assembly. I have, at the moment, left the rear washer jet intact, you can disconnect the tube and plug the hole up too but it works independently so you would then be squirting it to the inside of your car if you accidentally use it. Didn't like the idea of that so left it on the window for now. Maybe I'll get round to disconnecting the whole thing later but it's not doing any harm as it is. Or maybe I'll just point the jets at pedestrians...
