Passenger side circular air vent not working
I noticed this yesterday and I can’t get it to work. All other AC vents are fine. Does anyone have any idea on why the passenger side AC vent is not working?

Probably stopped working because it's broken? That's usually why things suddenly stop working. 
Are you able to divert air flow to the foot well and the windshield? If so, then you might have a bad diverter flap or an actuator. Not really familiar with the inner workings of the EQS HVAC system, but I'd imagine it's not that dissimilar from other HVAC units, aside from being all electric. Unless, of course,... Mercedes! and the engineers decided that every vent needs its own fan...?

I just figured out why it was not working. Evidently, my wife must have turned it off by rotating the vent. I had no idea that you can turn it on or off by doing this.
