The system is not working as it 'should' be, at least not in my experience with several makes/models of vehicles - unless, of course, you've personally been IN my specific vehicle and have some additional specific knowledge, you have no personal insight to make such a definitive claim.

When there is added thermal stress due to external radiant heat (i.e. from that big yellow thing in the sky), this vehicle does not appear to be responding as it should. In other words, it is not redirecting (increased) airflow through the dashboard vents. Airflow remains directed through the floor vents at a seemingly insufficient volume of air to properly regulate the cabin temperature.

All the best...

Then why don't you put the airflow selector to the floor and panel vent setting where it gives a mixture of the two?
