I have a 96 integra with the same rattle problem( driver's side ). I took the door panel off and found a weather strip inside door panel. I pulled it out, cleaned it, used a strong adhesive( 3m ), replaced the weather strip in the window glass run channel(left channel-closer to the door handle), rolled the window down and let dry for a couple hours. now the window doesn't rattle. so thats the problem with most tegs I guess. check yours and look for that fallen weather stip! good luck!
