A/C pressurizes cabin? it's a PLANE! cabin vents closed?

I haven't seen this, but here we go:

 

If i run my A/C for a few minutes...the airflow will drop drastically. and if i open the door, the air pressure difference makes it *POP* open. i also noticed that, when the airflow drops, i can crack a window and the air pressure will equalize out and the airflow will increase again.

I guess i should check if something is blocking the cabin vents lol

What happens when you press the recirculate button?

 

Perhaps something is block the return air intake, I would investigate that.
