Having watched also your video clip, I don't think anything is wrong. All looks perfectly all-right.
Unless of course you sense there's something wrong like I experienced once due to a bad tempture sensor built-in the CP. The airco couldn't keep the temperature set and that was revealed by not only a DTC, but also by the fan speed going up and down. Normally I hardly notice this part blowing air. Unfortunately this is type of break-down isn't unique and replacing means a new control panel (>640 euro new)
