Its an exit vent for the flow through ventilation system. It's a plastic grille like the picture posted above.
Look at any Barracuda factory literature and you'll see the theory.

I believe these vents also lent themselves to venting cabin pressure when closing the door with the windows up. You may want to consider not sealing them up tightly.jmo
