Which one do you think is logical help

friends I'm new here I have a problem hello to all of you
I press the button, which gives the digital air-conditioned air direction to the window, but it only gives the front, it does not give the feet and the glass.

please somebody come out and help me please

Well, someone who can help build a technical issue runs to the aid :)

I really want to tell you if I have an idea, but I will definitely hear you about the brillies :)

the control arm may be defective

At first, I was confusing the glass and head with the digital air conditioner.
