Hi all, got a problem with a 09 oct, the rear heated window isn't working, the switch is lighting up but no power to the window, if i run a feed to the window it will work, is there a relay somewhere that has stopped work maybe 

You checked the fuse?

On the earlier models the relay is on the on board power control unit. Later models are a different arrangement which I don't have to hand. Perhaps someone will pop up and say where the BPCU is mounted but I expect it to be near the fuse box under the steering column.
