Strange A/C Clicking - Please Help!

I have a 2014 Passat and recently have been hearing strange clicking sounds coming from passenger glove box. The sound usually happens when car is first driven, rarely happens at end of trip, and goes away when Climatronic system system is turned off. The sound is not terribly loud, all A/C manual controls work correctly and result in desired change, and the A/C system works without any issues. But not sure exactly what this noise can be coming from. I took the cover off from under passenger footwell where the A/C filter is and recorded the sound when car was started. The AC was blowing fairly hard at a time. Does anyone have ideas what this may be or how to further diagnose? How can this be fixed? Thank you all in advance!
