Hello! I have a 2010 F-150 crew cab and a couple months ago my panel vents stopped blowing air, doesn’t blow in the back seats either. All other vents including defrost and floor vents work great! Also, the panel vents don’t work at all, I’ve seen a lot of people have the same problem but they’ll blow on full blast, mine don’t, anybody got anything?

 

I'd start with checking the blend door actuator.
