Air conditioning stuck on defrost?

Air conditioning only blowing in the defrost position, won’t allow me to change the air direction. Any cheap hacks to fix this would be great. I’m thinking it’s the actuator hose but I’m not even close to being a mechanic. I didn’t grow up rich, but my dad always had me send the car to the shop growing up versus learning to fix it myself.
Now that our government wants to bleed is dry - money it tight, problem seems small, any helpful experience be much appreciated right now thanks!
