Are your vents actually broken or just sloppy and loose? Mine were just loose, so I dis-assembled them, cleaned 'em up, and then tigntened 'em up by using black self adhesive velcro pads to take up the "slack" in the joints. My units also had broken tabs which held them in, so I used double velcro to remount them. Velcro is very useful stuff around the car. Tod
