Plastic wall panel removal - E350
I just did this four times over the weekend. Start at the rear doors, driver side and pull the weather stripping back—you’ll see three or four black plastic plugs that need to be pulled out. This is the hardest part. Once those are out, yank on the upper trim, toward the inside of the van, til it pops out. They are press-fit and you’ll see the mounts once you start pulling them. Look for screws and remove screws, then pull. Pretty much the same on both sides of the van. I was surprised none of my mounts broke but the older the plastics, the more chance you have of something breaking. No big deal.
