The two grills at base of windshield by wiper arms (dont know what they're called) are held on with 4 ea square plastic clips. Does anybody know how to remove them? I tried pressing down on the center pins and they do go down but dont release anything.

Are these the applicable clips?

They would appear to be a one time use thing as it is not possible to pull the center pin up since it sits flush with the top.

As always, thanks for the help.
