First thing to try is a simple clean of the connector pins in the door hinge. Just taking it apart and remaking it sometimes works. After that you need to see if the current is getting to the door module. This is the computer module that sits under the window switch. It can fail, but again check the connectors to it first. It needs the door trim to come off to do this.
To get the trim off. Prise off the door handle front cover, undo the two bolts, pulr the panel off at the bottom, working your way up. Then lift up out of the window slot. Easier if the window is open, but you can't do that bit without power.
