Default Blend doors not working

I have a 2007 Silverado 1500 that both the temperature control and the mode switch does not work. The blower switch’s works, the lights on all three switches work, it’s just stuck on heat and a blend between defrost and blowing out the dash. Is there something common to those two blend doors?

Actuator is bad, you'll need to replace it\them. Common issue.
