Your missing what droptop mentioned. It's a duct outlet. Your main deflector unit, which is directly behind the AC controls and bolted to the heater box, has two lower 2" outlet ports.
one goes to the drivers side middle, the other goes to the passenger side middle.
I would give you mine, but the AC bug might bite me one day.
-if that outlet is not plugged, you are cooling air behind your dash. what a waist
