drivers window misbehaving

[samleeds]

I have an xk8 convertible and when I open the drivers door the window drops a little to clear the roof channel, then when I close the door, it goes back up into the channel. Recently it has a mind of its on. When I lift the outside door handle it chuggs down in increments and when I close the door it doesent go back up. Can anyone advise me as to what mechanism controls this so I can get it fixed because if i open the door and put the window up fully then close the door, the window fits outside the channel.

crisis averted. I just opened the windows up and down till they clicked and this was the resetting of the relays and now it all work s fine.
