What a nightmare went to put the nearside window down and nothing. Seems like it is the motor as the diagnosis included.
Pressing the switch without engine running - Relay could be heard
Checking the fuse.
Removing door card and wiring connector from motor.
Connecting multimeter to connector and pressing switch. Multimeter gave positive & negative reading as expected for up and down.
So in conclusion all fuese ok, power getting to motor. The only thing left is the motor itself.
Well it is covered on the warranty. Just the inconvenience of another day without the car.
