Today I realized that the rear air vents in the Model 3 are not active until weight is detected on the rear seats. It’s an interesting way of distributing airflow that I haven’t seen with the S or X.
There is a button within the A/C UI which allows you to toggle the rear vents even without engaging the weight sensors.
