I raised the window on my 2009 599 GTB (driver side LHD) and it seems to try and raise the window too high. The window closed and then there was a loud bang and now its not functioning. It is use the button I can hear the window motor (which sounds like somebody rattling a bag of gravel) but the window is not moving much. It I go for full lower it makes the nasty grinding noise and the window maybe lowers 1cm. Any help much appreciated.
