Massive thanks for the wiring diagrams!! They were a great help as is the rest of the maunal!!!
By way of an update, the switch is throwing out some weird voltage readings so think it could be that but still not 100%.
Just for the information logs, if the electrics do go and you need to raise the window, it is possible to do it manually whilst still locking it in situ. The whole door has to be stripped down ie: door card off, metal plate off, all bronze locator screws taken off. The motor and housing has to be removed from the silver facia and then using a 1/4" drive in the middle of the motor housing, the window can be raised maually. Just remember to leave a slight gap at the top as the window won't self-drop or self-raise if the electrics have gone!!! It's a bit of an effort and needed 3 of us to do it as one has to hold the window, one the motor and housing and the other wound the window up but as a short term solution it is do-able.
