AC Mode Selectors Don't Work

Hi! 2013 tacoma here. The AC mode selector does not work and blows out on face and feet no matter what the selection is on. I already replaced the mode servo myself which is what a mechanic recommended and still no luck. I'll need defrost in the fall where I live so looking to replace this over the summer. Any ideas?
