Monte Carlo knocking in the dash

I have a 2006 Monte Carlo when I turn off the outside air or turn off the car there is a knocking in the dash on the passenger side.

it could be one of the heater control doors moving to a neutral position. They sometimes make a noise when the gears start to get worn.

I have the same problem, and I have a 2006 Monte Carlo SS (Black & Grey leather interior). It's a common problem in these cars that could cost you anywhere from $300-$1000 to fix. It has something to do with a piece breaking off in the air cooling system.
