Hi. I have Audi A3 2013. My back passenger door won’t unlock or electric window go down. Would this be a fuse or electrical. Only problem is I have no idea what fuse box it’s in. Under bonnet or in the car and where to locate. Could someone share some knowledge on this please be much appreciated 

There is a fair chance the wires are broken or shorting out in the rubber bellows between door and frame. It is a common problem with the driver's door because that gets the most use, but it can happen in other doors.

As cliffcoggin says. I had exact same problem plus airbag light. Sorted by an auto electrician but could be a diy job.
