Help... strange noise on my c32

hey guys I have recently bought a C32 AMG. And everything has been working. All of a sudden the car started making a strange noise when I turn it on. It is coming from the lower dash area on the passenger side. It sounds like its throwing spurs of air. It only does it when I initially turn on the car and after a little bit it stops.

Does anyone know what it could be?

I would say it is a stepper motor. I had the same problem causes no harm but the dash must come out to fix to the tune of $700,it is a common problem.

stepper motor linkage.

$13-50 fix if you DIY

$300-500 fix if you have a shop or dealer to fix it

if you have the original factory warranty still, fix it NOW!

There is a real good DIY in the C-Class W203 section for the stepper motors, you do have to remove a lot of crap to get to them. You are paying primarily for labor if you have the dealership do it. It is a minor inconveinence but embarassing when friends ride with you. Basically they control where the air flows through the vents in the HVAC system.
