What is your question?
The rear a/c is working fine and the air is blowing through the rear vents. If I put the front a/c to blow on the floor, it works. But if I change it to blow into the face, nothing comes out. Last time this happened, when we closed one of the front doors, it started working. So, is there a loose wire or a bad fuse?

Possible vacuum leak under the hood at firewall. small hard plastic vacuum tubing that goes through the firewall may be split/cracked/acid corrosion if they still do the newer Expeditions like they use to. common problem on the older models for this,but most of the time the air would default to the defrost mode? also copy and paste the link below,not sure about it. https://repairpal.com/ac-fan-speed-changing-constantly-793
