1999 Ranger 4 X 4 Heat / AC / Air only blows through floor and dashtop

My 1999 Ranger has 78000 miles and the heat / ac only blows through the floor and defrost vents at the same time. It will not blow throught vents on front of the dash. What could be the problem ?

Yep, look under the hood most likely on the right (passenger) side near the firewall for the leak. If no luck there, listen inside the cab around the switch area to the pass side floor.
