Recently my ac on my 97 Chevrolet c1500 4.3 the ac tends to blow out the feet vents instead of the face vents where it is set at. I replace the blend door actuator because I noticed it wouldn't stay in the same spot after setting it to blow on the face only but yet still have no luck. I don't hear the "normal" tapping from the ac vents from when the doors fail so I'm not to sure why it's still blowing through the face and floor vents when I only want it to blow to the face. What else should I check or do I need to just take apart the whole ac setup in the cab to figure it out
What makes this problem better or worse?
Nothing

Possible problem within the dash control unit - visual inspection of actuators while mode selection is being toggled may help.

Good luck!
It rotates about 90 degrees going through all settings but fidgets randomly when on one setting so it's most likely the control unit right?and I just checked if I pull on the rods individually they both function fine and one closes the lower vents so I'm pretty certain the vents inside the box are fine. So then the last thing to check would be the unit I assume
Its wired
Since you said actuators is there more than just the one on the driver side
