Naj,
This info came from the other site. Let me know if you have any questions.
Here's what to do once you have the door apart and the window out:
1) Note where the guide jaws used to be. You'll need to be able to replace them exactly where they were originally installed. There should be some felt and residue from the old epoxy to give you a clue. Mark the location with a razor. Clean the window throughly. Use the razor to remove old guide jaw adhesive and felt.
2) Clean the guide jaws. You might need a degreaser.
3) Replace the plastic clips in the guide jaws if they look worn.
4) Cut 2 squares of thin felt to line the guide jaws. Mix up some epoxy and
use it to attach the felt to the window. Allow it to dry overnight.
5) Apply more epoxy to the felt. Push the guide jaws into place. Allow it
to dry overnight.
6) Clean the window rails and spray on new grease. This is a good time to
re-lube the window crank as well.
7) Drop the window back into place and adjust so that it doesn't gap and
doesn't break when you slam the door. I think there's another article
covering window adjustment.
Use a rubber mallet to gently persuade the the trim back into place.
