hi there is a clip behind the winder and make sure that you have took all the screws from the ends of the door card and then once the winder is off you just pull the the door card off as it will be only helled on by the the pastick clips behind the card its a easy job mate but if water has got behind the winder in the door the rust will swell in the winder an then its a sanner job behind the winder...................hope that helps
