Hi all just bought a sceptre Mark one and the screen washer does not work, I have been told You push the wiper knob in to squirt it but it don't work ? I have checked the washer motor and that works so I assume the button must be faulty or the wiring to or from it,does anyone know how to get to the back of the switch ? Thanks in advance
Oh and ps is there a fuse for it ?

The original Mk 1 had a push button wash. If you have a pump, then that has been retro fitted, and probably has a switch somewhere else. In all likelihood the original push button won't be connected anymore. If the pump was correctly fitted there will be a fuse, but I guess you have to find the switch first! Hope this helps...Paul.
