2022 Model 3P rear ac vent not working?

[Tes3P]

My rear ac vent does not flow when I turn the ac on unless I put the ac in Doggie mode first. It will then stay flowing when I turn the dog mode off. Is this really the only way to get the rear vent to flow? I've tries the owners manual without help and every control I see on the screen.

Put someone in the back seat and it will work.

The backseat vents turn on when there is pressure detected in the rear seats. If you have someone / something back there and have disabled the seatbelt warning sensor it may not trigger the air-conditioning - I'm not actually certain how that condition works.

It will not turn on automatically unless someone is sitting in the back. You can turn on the rear fan manually in the climate menu.

Previous poster is correct. I often turn on the passengers's side and rear airflow when driving alone.

It's all done in the Climate menu. Just tap the HVAC controls on the bottom of the screen. Tap the passenger's side dash (where the air would come out) and it'll turn on. Then switch to Rear (on the left side) and tap the On button.

Thanks to all for this info! My problem was getting vent air to my dog. She is then not heavy enough or in the proper spot to activate the vent.
