Hi , I am having an issue with my o/s window . When I press the window switch the window only seems to want to go upeven if I press the down part of the switch. So I stripped the door down to have a look , but everything seems in order with no broken bits. The only thing that seems a bit od is that the mechanism is stiff to turn by hand. And the motor only turns in one direction. I replaced the window remic about 5 month's ago. Any advice would be greatly received ?. Thanks.
