Passenger window won't go up or down on the switch, nor close by going up when the door is shut when driving.

Locking the car doesnt close the window either so now water can get in when it rains.

The passenger wing mirror still works as usual from the centre console.

Unfortunatley the car just came back from main dealer after very expensive and slow passenger door repair so im not keen on that again.

Is this likely to be the door module or the motor? How can i diagnose the issue?
