2004 explorer rear heat and air

[Tjmiller944]

The rear heat and air in my 2004 explorer blows very weak. The air in the front blows very strong. Any thoughts would be great thank you all.

Is this with the front controller or controlled from the rear. Mine blows pretty weak if I control it from the front. But if allows to use the rear controller it blows like a hurricane.
