Could well be the car has had a new boot and the wiring hasn't been done.
Look behind the O/S C pillar trim and see if all 3 plugs are plugged in then check they are getting voltage at the appropriate times.
Then take the panel off inside the boot and check the wiring there. There's only 2 wires for the locking and 4 for the wiper motor plus 2 for the heated rear window.
If your definitely getting voltage to everything at the appropriate times then check the earth point on the N/S C pillar
