Knocking noise behind dashboard

Is anyone else getting that knocking noise when you turn on the car? It only knocks for a few seconds then stops. Sounds like it's coming from behind ac.

That's to wake the hamster that runs on a wheel that produces the electric charge needed to start the car.

Seriously though, no, I can't recall hearing a knocking coming from behind the dash when I start the car. Just the usually. Fuel pump turning on, radio coming on, then starter turning over when the ignition is keyed. Is your a/c on everytime you start the car? If so, try starting it with it off.

When I start the car with the ac in the on position it doesn't knock. When I start the car and then turn the ac on that's when it knocks for a few seconds

Its a blend door. Mine did that about a year ago. It was covered under warranty.

Does it sound like that? Looks like the video's comments point to the A/C or Blend door actuator.
