I've just found my rear offside window is not working and the switch on the door is not illuminated. Any clues to get me started tracking the problem down?

Thanks guys.

kinked wire to the front door / or rear door. I think that the front, as they started opening.  -> as the front door unit controls the rear door units

Thanks. I'll have a look when i get home.

I realise now that the door itself does not lock either!!!
