My friend has a Ford KA and the passenger electric window will open about 1 inch and stops. It seems it is leaning towards the left, so it doesn't go down that 1 inch completely straight down. Could someone suggest what might be causing this please and let me know what action to take. I believe it could be the mechanism that the window sits on, but wonder what I should do to rectify this. Also, does someone know whereabout/ what part might need replacing. From feeling for it, it looks like it is around the middle section, but I cannot get a clear view as a panel is in the way that cannot be removed.

Thanks

Greg
