To remove the weatherstrip, we grabbed the upper end and slowly pulled downward and around the door. If possible, keep the weatherstripping in one piece during removal. If it breaks, it's sometimes a little difficult to separate it again from the door because it is often glued in spots to the metal. If it does break, carefully use a screwdriver to separate it from the door. After we removed the weatherstrips, we removed the old nylon anchor pins with a pair of diagonal cutters.
