SOURCE: a/c problem
You either have a bad control, or motor running the air direction door in the front HVAC unit, or a door that is stuck.
The front and rear units are totally separate.
The door directs where the air, cold or hot, should come out, whether it is panel vents, floor, defrost, or any combination of those.
This door and motor are located inside the heater box which usually requires a lot of the vehicle dash assembly to be taken apart to get to these parts.

There is a flap in your heater box that is controled by your vent switch by your heater controls. listen for a vacuum leak. that is common and hopfully the problem. there is vacuum lines that control the vent door that redirects the air to your vents.
Has your dash been messed with recently? if so i would check there first. you should hear a hissing if thats the problem.
Otherwise these also are common for that door flap to break and not switch NE more. thats the only 2 things that i can think of off th wtop of my head to be the problem. this would require the whole dash to come apart if its this problem

common problem, check under dash by the gas pedal if control arms are muving went selecting from ac to heat cuz this it is the control for the vents to go from ac to heat and to defrost.

It sounds like you have a blend air door stuck. This is in the housing of the heater a/c blower unit under the passenger side of the dash. There is a motor on the top of the housing that could possibly be stuck or on working.
