I had a new regulator fitted to my Picasso and the window only goes up and down in stages now. Can't think of what could be wrong.I've sent the window up and down several times but it's still the same.
Anyone have any ideas?

The following is the reset procedure for Mercedes.
It may be similar for your car.
Press and hold the button until the window is fully open, then hold for a further 10 seconds. release and then close the windows, hold again in the closed position for 10 seconds.
Worth a try.
