Looking for a replacement part for the automatic window of a 1994 Chevy Cavalier RS. It's a round piece of plastic about an inch wide and a half inch thick that pops on to the mechanical arm of the window and slides into the groove. It rolls back and forth in the groove, raising the window up and down. I can't find it on any of the sights I've googled, and there aren't any junkyards in town. Looking to order online, once I figure out what it's called.
Another thing to try is a glass installer--they sometimes have an assortment of these on hand in case they run into a problem installing a door glass....try to talk to one of the installers personally not just someone that takes the phone orders.
Good luck.......Paul
