when did it start ? did you have a dead battery ?
try pulling the fuse for the ac system (climate control) wait 15 minutes, plug it back in start the engine, let it run another 15 minutes & recheck. hopefully the mode door is not broken or stuck.

Very common failure unfortunately. The most common failure is the material tears and gets wound up in the mechanism then things just get jammed up and can't work.
Advice to consider IF, stress IF, this is your problem. The whole dash has to be removed to get to these things. It typically costs about $1500 with all the labor involved. SO, you should seriously consider replacing ALL 4 at the same time, to avoid another $1500 bill when the next one fails in a few months, or next year, or whenever. The others will fail at some point. The extra parts cost to do all 4 is only about $200.
The possible good news is that other members have reported that the new replacement doors seem to be a different material and are a different color so "hopefully" they will hold up and last longer than the originals.
Here's a pic of one just for reference.

There are 4 "mode doors"/actuators in the HVAC system that open and close to direct air to the appropriate place based on the control settings you input with the dash control.

Anyway, if you're going at it yourself here are a couple DIY's that should help:

And another thing you might try is disconnecting the battery for 10-30 minutes. In a very few cases that reset everything and it worked properly.
Good luck.
