Using a flat-tip screwdriver, push the front hook (A) from inside of the door, then pull up the front portion of the rear door glass outer weatherstrip (B).
Release the weatherstrip from the rear door outer molding (C) by sliding the weatherstrip forward, then remove the weatherstrip.
If the clips are damaged or stress-whitened, replace them with new ones.
Set the rear end of the door glass outer weatherstrip to the rear door outer molding. Before installing the weatherstrip, align the clips of the weatherstrip to the flanges where the clips should be engaged by sliding them.
Push the clip and hook portions of the rear door glass outer weatherstrip into place securely.
Reinstall all remaining removed parts.
NOTE: When reinstalling the door panel, make sure the plastic cover is installed properly and sealed around its outside perimeter to seal out water.
