Where does air vent out of a an '80 coupe?

[try2pas]

I am trying to get a handle on minimizing air noise in our '80 coupe. When you bring air in via vent or A/C or heater air; where does in then vent OUT? You can't bring in air if it can't escape out. Maybe our "out" is blocked off or something. Does anyone know where those "out" air vents are located?

On my 81 there aren't any OUT air vents.
On any car I have had, with the windows closed it's not easy to get enought air in then with a window open.

There are no exit vents, but the interior is also not air tight.
