The other half has an old focus (02 plate) and the O/S/F electric window has gained a mind of its own. It will go down and usually refuse to go back up. When it does it might stop and then the next 'up' press will mysteriously send it back down again. On other occasions it will work fine.
As far as I know there is only a switch and a motor in the door and the motor is working obviously so that would mean a switch right? But it seems to do it when it's damp which might suggest that its water getting into the motor connection.
Has anybody else had this problem?
