I noticed the release button on the driver's door armrest cubby was loose. Then when I opened the lid to put something inside I noticed the button slid right out. I could tell a post or two was missing on the inside of the button. It stays put when the lid is shut, so I'm just careful to not lose the button but was hoping I could replace just the release button and not have to buy a whole new door panel. I've attached a picture so you know what part I mean. Is this a separate piece that can be replaced? If so does anybody have a part number? No yards by me have this new of a Town Car available to pick through, sad to say.
