If the TSB doesn't resolve it there might be a few other things to check:
1. Is the door aligned correctly to the body? I would check for scuffing on the paint around the door.
2. Might also be the header molding on the door not being clipped in correctly. If you grab the molding above the glass and try to rotate it, does it move and make noise? It shouldn't.
