Passanger side at base of console towards the firewall there is a cover with a plastic pop screw holding it in place. Once the pop screw comes out how do you pull the plastic cover off? I'm afraid to force it for fear of breaking whatever is holding it to the console piece. I belive behind this cover is the heat/ac duct and I want to look inside for a noice I belive maybe coming from this area. RX300 1999 Any ideas, thanks.
