Yes,
The noise comes from SERVO motors which adjust flaps in the ventilation system. Mine has four and as far as I can tell they are all different. To replace them is quite a job. Most of the sections on the bottom side of the dashboard have to be removed to get to the servo motors. Mine have three on the passenger side and one on the drivers side. The one that makes the noise when you start up the car is on the passenger side behind and under the glove compartment. You might want to replace all of them since if one is making noise the other ones will soon follow.
Good Luck!
