2000 S40 Drivers window not working

[Phildent]

HI everyone,

First of all thank you so much for this forum, it is always a great help.
Well, the drivers side window won't go up or down.It suddenly stopped working. The motor is working but the window is not.
I have taken the door trim off and can hear the motor whirring, but the window won't go up or down.
I have learned to ask expert advice before I strip the motor out. Can anyone help me with advice/next step please.
Thanks
Phil
