Before you spend money buying parts trying to fix it, look for a disconnected or damaged vacuum line under the hood. The dash controls are operated from a vacuum supply from the engine. Without an adequate vacuum supply the vents may not operate correctly if at all.

Why won't rear air switch from roof to floor vents in a 2003 ford expedition?
There is a motorized switch that changes the position of a large flap inside the air handler above the right rear wheel. There is a small gear train between the motor and the gear. The pinion gear has stripped or the switch is not receiving the proper voltage. My guess would be that the gear train is damaged.

The motor actuator is bad that redirects your airflow when you change modes (auto - manual, etc..) You need to remove the right side wall paneling from the rear up to the aft right door. This is where you will find the actuator connected in the system. They are about #30 from the Chevy dealer and not an after market product.

This is the same on all cars. When the air flow is OFF in a section, the it blows stronger to the other vents. In this case the ones for the windshield. This makes defrosting quicker so you can start driving safely sooner.
