Heat in middle / rear only when driving.

My 2021 Suburban blows hot heat in the front row without issue. In the middle / rear rows, it only blows heat when driving, when I stop or park the air gradually cools. Any thoughts?

with the engine running?

The temperature blend door might be getting stuck.
It's a warranty issue. Take it to the dealership.
