There are several doors...
 
That most likely was a recirculate/fresh air door.

There are 4 of them...
 
ORN orange is recirculate door
WHT white is the bilevel valve for AC and floor. White vacuum only gives floor I believe.
GRN is the other end of the bilevel and when it's on with the white the valve is held midway and the air goes to AC/defrost direction AND to the floor for bilevel.
BLU blue is the valve for defrost that closes to force air out dash ducts.

Nope.
 
The orange goes to the recirculation vacuum motor over above the driver's pedals. It lets the air from inside the car be mixed with some outside air and blown back through the system. I think that is probably the door you could see with the blower motor removed on the firewall.
 
The dash vents are the defrost door. It closes the duct going on up to the defrosters and makes the air come out the dash vents instead. At the same time the bilevel vacuum diaphragm is closed so no air goes out the floor vents; that means the air is all forced to go up toward the defrosters.
 
Do you have a problem? Is there a specific question or purpose you have? If I know your point, I may be able to help give you answers better.

What kind of AC do you have? The digital readout with numbers for temperature settings? Or the stand type that just has a lever you move to adjust warm to cold?

You have not stated what the problem is.
 
Saying everyone you know has the problem means nothing to me as to what your problem is.
