I think your problem is the head unit that selects where the air comes out ie. Face, floor, defrost, or hi-level face and floor. If that's not working then it will not let you switch location that you want the air to come out.
my issue at the moment is that the linkage (control arms) have come apart. it looks like there's a part missing from between the two control arms. there's a small electric motor with one arm and another arm that controls a flap somewhere that shifts the air flow between floor and up top. both of these control arms have a square hole in the ends and i don't see a way for them to be reconnected. so i'm assuming that there's a part missing.
Your vehicle uses electronically controlled blend doors to direct th air flow from defrost to vent and to the floor . If the door motor is bad then it will stay at a fixed position so you will not get the air to flow out the defrost ducts. There are at least two of these one for air blend and one for fresh air. They are located on the passenger side usually under the plastic cover and have a wire harness that plug in and are usually shaped like a piece of pie.
99% of the time when they do that it is the control head. that is the thing you adjust all your temp settings on. have to purchase from dealer. have last eight digits of vin # when ordering.
THE COMPRESSOR IS SUPOST TO RUN NOT MATTER IF IS IN HOT OR IN COLD MODE SOME TIME THERE IS A POSITION WHERE THE A/C WILL BE OFF AND THIS IS ON THE KNOB CONTROL WHERE YOU SET DEFROST AR FT VENTS
ALSO ON THE THE SWITCHING FROM DASH TO FLOOR CHECK FOR ANY VACIUM LEAKS FROM THE ENGINE COMPARMENT SINCE MOST OF TIMES THIS IS CONTROLED BY VACIUM ACTUATORS
