This sound is normal if you have the re-circulate button depressed. This control activates a vacuum modulator that closes the fresh air door. When you turn off the key, power is dropped to this solenoid, and vacuum is released, and thus the fresh air door opens. This is the sound you are hearing. Now, if you are getting the sound when your re-circulate button isn't depressed then you may have a bad switch that is causing the hvac system to go into re-circulate mode even if it's not selected.
