HVAC Vents when no passenger

[tstolze]

The passenger side vent is shut off when a passenger is not in the car.
We have noticed this in both our M3's, and it seems the cars don't cool well/fast when it's hotter than the mid/upper 80's.
We do bring up the HVAC control and turn the passenger vent on which solves the problem.
Anyone found a way to override this behavior?
I would think they could tie this preference to your profile.

That’s an irritation for me as well… I just enable passenger and rear every time I drive for now.

I just posted a similar question along with another. Hard to believe that there are no solves for this. In south Florida, this is a much needed feature.

This feature was added to the 2021 Model 3s with the heat pump. Both of my vents are on all the time.

HVAC Feature Not Available on US Model 3s?

So yesterday I was watching one of TeslaBjorn's videos again and he was doing an efficiency test between the 2021 Model 3 SR vs the 2019 Hyundai Ioniq. Anyway in the video at 4:51 and 19:46, he shows and says that the Tesla can detect when you have one person in the car and only activate the...

All the time? Automatically, or you have to activate the passenger side on the screen?
I asked the service advisor, and, indeed he claimed a link between the heat pump and the lack of automatic full frontal. Can anyone explain that, though?

If there is a passenger in the car the passenger vent is on, if there is no passenger the passenger vent is turned off and you have to manually turn it on by touching the vent on the touchscreen.

I am aware of that. My question was in reference to Gasaraki who clams both of his vents are "on all the time". Had he found a way to set that automatically, regardless of passenger occupancy? My second question was: what's the link between heat pump and lack of passenger venting? Is this the only way they can claim the 315 mile range on 2021 M3P?

On all the time. No need to press anything. I don't have a heat pump in mine. Every pre-2021 has the vents on all the time. (Except for the back ones)

Sometimes I turn on the passenger vent when no one is there, by simply touching the area used to direct the air. Is there a way to turn OFF the passenger vent once it is on when no passenger is present?

It does it automatically, don't know after how long or next drive.

I turn off the HVAC completely then back on and passenger won't be on if no one is seated there
