Hi i've just bought an '02 Mondeo which has an electrically operated height adjustment on the driver's seat. When I press the switch i can hear the motor going but the seat doesn't move. It is currently stuck at it's highest point. Is there any way of manually lowering the seat? I'm not too fussed about fixing it as long as I can get it back down to it's lowest height setting. Has anyone had this problem before? What did you do?
