Repairing your vehicle door window seals requires locating the correct replacements for your vehicle year, make and model. The black weatherstrips on either side of the window are called "felts," "sweeps" or "whiskers," and you can find them at your auto parts store. These weatherstrips attach to the outside top of the door and on the inside top edge of interior door panel. Remove the old weatherstrips, clean off the old adhesive and replace.
Take pictures or videos of the original weatherstrips before you begin. Refer back to them as needed.
Remove the old weatherstrips, using a screwdriver and pliers. Do not scratch the paint.
Remove all adhesive with alcohol and a shop cloth. Use a plastic scraper if needed for the really stuck-on stuff -- a plastic scraper will not scratch your vehicle's paint. Wipe down one last time and let dry.
Apply new adhesive and install new weather stripping. Wipe away any excess adhesive.
Replace all your vehicle weather stripping now while you have all your tools together and are committed to the project. Remove the strips on one side only so you can refer to the other side if needed. You may find that you need to remove the interior door panel. Save all original hardware in case it is not included with your new weatherstrips. Save all receipts.
Some adhesive can be hazardous to your respiratory system. Ensure adequate ventilation.
