Unable to Change Air Flow Location

I have a 2016 Ford Flex SEL with 140k miles on it. It started a few days ago but the air is stuck on defrost. If I change it to any other option, it does nothing.

I am pretty sure I will have to have one of the actuators replaced in the dash.

Has anyone had that done and can share the price? I am just trying to figure out how long I can go with defrost only 😂
