There are two motor controlled doors that control air flow for your heating/cooling system. These doors are located in the A/C ductwork under the right side of the dash. When you turn off the ignition, the doors close through the action of the small electric motor and gears is an attached control box. The knocking sound that you hear is a gear slipping in the control box as the control motor continues to run after the air door has been closed. I have no idea why the door motor continues to run. The solution for me with my 94 burb was to disconnect the electrical lead to the control box. If you have lots of patience and very small hands you may be able to replace the offending module. However the root cause seems to be the door motor continuing to run.
