Question 1994 E-320 heat and air?

Hello everyone!
For the last couple of months when I turn off the heater or ac in the car I hear a loud flap or thump which I think is the door that redirects the air. I am curious if there is some type of vaccuum device that controls this and if it might have failed and a good starting point on where it might hide?
Thanks in advance for any help.
