Usually a sign of a faulty blend door under the dash.
The blend doors direct air thru the ac and heater core along with the upper and lower vents.

Usually a sign of a faulty blend door or problem with the control on the dash. The blend doors direct air thru the heater and ac then thru the selected vent outlets.

change your cabin air filter, it is probably clogged not allowing air flow. see your owner's manual for instructions. I hope this helps

its a problem with the switching mechanism. you have to look up under the dash to see if you can see where the switching mechanism is. if you can not see it from there youll have to remove complete center dash

If it blows thru other vents, your air ducts may have come loose. If you don't get any cool air, your coolant is low (it evaporates during the time and below some point it will not circulate anymore). Also the aircon blower can be faulty.

sounds like bad acuator motor, this is what moves the door in heater box to set hot or cold air, and other motors to set air to blow thru defrost, vent or floor. good luck.

check or loss of vacuum to mode control switch in dash ac control. these are not blend doors, they are air flow control, a blend door controls the air temperature not where it comes out.

climate unit is bad

Just had the same problem. It was a broken vacuum line on top of the engine. Check all vacuum hoses, and especially the one that goes to your pot. You should hear it hissing when the engine is running. If not, wiggle them around until you find one. Let me know how it goes.
