Hi - attached video to capture the sound.
Hear vibration when fan is running. Plus with AC, periodic hissing / clicking on and off - which occurs every 10 secs or so.
Driver side vent has no issues - normal airflow sound.
The dealership has inspected and says all normal operation. Thanks for any guidance please if anything for further attention - all vents should sound the same?
Edit: Driver side vent for comparison:
