Check the fuses and also the connector betewen the door frame and the door - it does undo and is l'atched' - you'll see what i mean when you try to undo it.Hi, Did you find a solution to the loss of power. I have exactly the same problem and was wondering if it might be a fuse?.
Often the problem is a connector block that has come apart inside the door - not as bad as it sounds. the connector is a push fit so over time can work loose - a dab of silicone sealant will keep it in place in future.
you need to strip the door card off - takes around 2 mins to do, you need a Torx (cannot remember the size and an extension because the torx screws are buried in the handle. it takes care and a little brute force to remove the handle cover to access the screws (2) then the card simply pops off. the connectors (black and brown) are close to the handle.
