2012 Nissan Pathfinder Silver A/C issue

[agcovey]

Here is the problem. The day prior everything was working just fine, but out of nowhere the next day my passenger A/C is not working. I turn the vents on and I am getting airflow, but just the passenger side A/C is not coming through. My temp can be set 60-90 degrees and the driver side defrost, head, and feet all work, but on the passenger side it IS NOT coming out as A/C, its hot as hell. The rear vents for back seats are getting A/C but strictly passenger is just engine heat/outside. Ive opened up mostly everything, looked for cracks in tubing in engine bay, etc. I'm not sure if its a directional issue where a valve isn't closing or opening, or if its electrical with the thermometer, wires, what not. I have no idea and it sucks. I haven't gone to dealer or shop just yet. Any ideas or similar issues?
