The vent I mean on top of the radio. The mode switch can be off, blower to feet, blower to face, blower to feet+face. It give "GliGla" noise when set to last or feet+face blowing mode.
I watched some videos, there seemsof two small motors? look like the mechanism cannot engage both blower channels?

Servo motors.

thanks. but there seems of two motors, and, if motor issue, why I choose one direction blower works fine - either blow down or to front. Only when I choose blow down+front I got the noise
