One of the fins is rattling on the passenger side vent in the dashboard and is very annoying. I would like to know if there's anyway I could pop that sucker out and either fix or replace it without damaging anything. I would bring it back to the dealer because it's still under warranty, but it's a pain in the butt for me to make an appointment and leave my car there. If I could fix it myself without too much trouble or cost, that would be great.
Thanks in advance,
John
