There are several screws hidden to remove the door card, these are behind caps. There are 3 along the bottom, 2 in the door pull, etc. Then the door card is held on by fixing screws that pull off, becareful not to bend thye door card. And before you pull the door card off the handle winder needs to come off properly, you use a piece of cloth inserting it behind the window handle to release the clip that holds it on and remove it from the spined shaft. From here you should see anything you like and should be able to do anything. I am sorry if you find this difficult to understand but it has been described to the best I can. I am more than able to do this job and have done many times, so I do know what I am talking about. E-mail me if you have any problems. trit666@hotmail.com .
Kind Regards.
