Passat electric window problem

passat salloon 2.0 auto M reg

the front left passenger window won't go down.
If I take the inner panel off the door and press the window switch I
can hear a small click, I've tried using one of the other switches
from the car and the same thing occurs. I presume then that the switch
is ok so the problem is the motor. Can't see or find any fault in the
wiring.
The manual says there could be a fault on the thermal cut-out but I
don't know where this is. Anyone know?
Also when it comes to removing the motor the procedure is to first
remove the regulator, by first lowering the window so the regulator is
visible through the aperture. How can I do this though when the motor
won't work, is there a manual way to lower the window?

thanks for any help
I'd like to check thoroughly because a new motor costs £131
