2010 t&c blend door actuator
 

I believe that i need to replace one, maybe both, of the blend door actuators on my wifes '10 t&c. It seems like the most likely culprit for the clicking she has as i can hear it coming from the right area and i am pretty sure i can feel it when i am touching one of the actuators.

anyways, the replacement seems like an easy process, but now i am reading about having to recalibrate the hvac system after replacing them, but the diy recalibration was apparently removed on the 5th gen vans.

can someone give me some guidance on this?
