Shut off ignition a loud tapping/knock started from top right hand side of passenger dashboard for about 30 seconds?

After I turned off ignition the noise started each time. It went away after 30-40 seconds!

This is the air actuator and can be accessed if you drop your glove box down. Same thing happened on mine. It was like 30 bucks at an auto parts store. A non-OEM part has been made and is cheaper that way look around if someone quotes you 60+.
