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.

Why does my air only blows out my front vents and not the floor or defrost on your 03 dodge ram?

Not knowing what vehicle you have, many vehicles use vacuum to operate some, if not all, the HVAC (Heating, Ventilation, Air Conditioning) controls. If the vacuum supply is cut off for whatever reason the HVAC goes into defrost mode. I suspect you have a disconnected/broken/damaged/pinched vacuum supply line usually found under the hood leading from the engine into the firewall.
