Heat not working in truck. '17 F150

The heat does not blow warm air into the floorboard area of my truck. I can hear the blower motor running. When I switch it to defrost or vent, the air comes out the appropriate area. There must be an air flow director that switches it to the 3 sources (defrost, vent, floor) but for some reason it won't switch to the floor. Any idea how to fix it? It snowed last night. TIA.

Check the coolant level ASAP

edit oops didn't read

Its probably a stuck door in the duct work that controls where to blow air. I'd wait until it gets over freezing then it'll work. Moisture in a vehicle from snow getting inside like on your boots can cause stuff like that to stickk until it gets above freezing

Don't hit at all if it is honorably possible to avoid hitting; but never hit softly.

Awww, come on guys, it's so simple maybe you need a refresher course. Heyya! It's all ball bearings nowadays. Now you prepare that Fetzer valve with some 3-in-1 oil and some gauze pads, and I'm gonna need 'bout ten quarts of anti-freeze, preferably Prestone. No, no make that Quaker State.

Found on road, disabled. I'd rather be Strokin than Cummin.

It's the 5.0 V8.

Blower motor door actuator/ blend door issue.

Typical Ford problem. My Grand Marquis had an F-ed up blend door and it would go between hot and cold constantly. On most of them you have to take the whole dash out to get to it and replace it. 7 hours worth of work for a $40 part. Pain in the dick.
