My Repair & Advice
Following the YouTube video posted by your site, I Removed the cover, popped out the retainer, removed one screw and replaced the defective part. However, I did this twice, replacing the one on each door and each time you have to insert a flat head screw driver into a slot on a plastic retaining clip and pry. Each time the plastic piece broke making it almost impossible to remove the clip. That should be addressed on the video.
