2004 Hyundai Sonata 4 cyl Front Wheel Drive Automatic 150k miles

I have a 2004 Hyundai, when I try to change the air circulation by pressing the button for face, or leg or
front or windshield, it seems to stay on windshield and and legs no matter what button I press it will not change.

yesterday I tried and it start working again then it got stuck on only legs and front for vent. Is that a fuse or the whole unit? No clue why? Maybe minor fuse?
or the interchange?

Chck for continuity between terminals with the button depressed according to the modes specified.

If continuity is not as specified, the control panel is bad.
