Hey recently my driver window has popped off track. I've been looking for a replacement but cannot find the part I need or the exact name of it. Hoping some CL sc300/400 gurus could help me out. At the bottom of the actual window there is a little hole in the glass on both ends along the actual window slides that go up and down. Along those slides is a rubber nipple that pokes through those holes in the glass and is what pulls the window securely up and down the slides. Well one of those nipples seems to be worn out and keeps popping out of the hole causing the window to not slide up the tracks smoothly and securely. Not really sure what this "nipple" thingymabob is called but can't seem to find a proper name or part number to get a new one. Any idea what this is actually called or a part number I could use to replace it. Not having a window to roll up and down is a real pain in the a$$! Thanks for your time CL. I am NOT referring to the guide in the middle of the window that is attached to the window motor for clarification. It is the slides at both far ends of the window.
