2008 Jetta no heat from center vents only was created by EricGoodrich

Hi everyone. Hopefully someone has an idea on this one.

08 Jetta. 80 degrees from center vents, 140 degrees from floor vents. Symptom is no heat from center vents.

Blend door actuator moves to middle position when mode control is at face vents on Max heat. When I move mode control to floor, the blend actuator moves to Max heat on its own. I've checked min/Max/actual position values with my Solus and the numbers jive. Is this a logic problem? What the hell is going on here?
