Oh my word, thanks so much for the info, I will let you know how i get on.. Thanks Again...

Brief update, weather has stopped me working on this so far, but managed to get a look behind the door panel.
As far as i can see and hear the mechanism is clicking and sounds like its working but still not locking/unlocking so im guessing i have been sold a faulty unit.
Will keep you posted, thanks.

Problem solved, took forever to get round to this but was a faulty unit sold to me.
