Step 1: Remove Old Weatherstrip

Step 2: Install New Weatherstrip

  • The weatherstrip is side-specific, so grab the correct side you are going to start working on.
  • Start at the top section of the door and feed the weatherstrip in between the glass and C channel.
  • Once started, feed the weatherstrip all the way to the bottom while making sure it is seated correctly.
  • Seat and align the top of the weatherstrip to the door frame. Use the 3M adhesive to get any sections held in place as needed.
  • Align the holes of the weatherstrip with those of the door and install the rivets or push pins.
  • After everything is in place, test to make sure the window can roll up and down freely.
  • Reinstall the mirror covers and door panels.
  • After this, you are good to go!
