Blend/mode door motors

So I’ve got a 2007 mustang gt and when I set my mode on my climate control to feet and while driving it would cycle from feet to defrost to face, and whenever I set it to any modes that involves feet it cycles like mentioned but if I put it on defrost only or face only or max a/c I do not notice it cycling. Would the fix be a mode door actuator or could it be something else relating to a control module of a sort I’m a new tech and am trying to expand my knowledge on stuff like this and proper diagnostic steps.

Here's my write up for replacing blend door actuators:
That said, your story sounds a little confusing but it's possible one or both of the first two actuators mentioned in my write up may have stopped working.

The operation and diagnostics for the 2005 climate control system should be similar for your model year.

So when I select feet only it will cycle through vent, floor, defrost and it will intermittently do that. Then if I select feet and face it will work fine mostly and occasionally do the same thing then if I select feet and defrost only defrost works. But any setting that does not relate to feet in the mode works just fine.

Could a bcm or something be a possibility I’m not sure how these 07 mustangs are set up haven’t checked it out mechanically a bunch like I have my other mustang
