Not sure why previous poster showed you how to fix a switch in the door, but anyways.....
I had same problem as you.
My Yukon has the single overhead door, not the "barn-doors", hopefully yours is the same. Open rear cargo door. Using a trim tool (buy the set from Harbor Frieght for less than $10) remove the lower trim (at carpet), upper trim (at headliner), then the right pillar trim (mine has small Bose speaker in it). Loosen trim between passenger side back door and the cargo area main right rear trim. Remove main cargo area right main panel, by unscrewing the big black know, prying out the small plastic plug, and carefully disconnecting the AUX power plug (looks like a cig lighter outlet) once you can get behind the panel a little bit.
Now you are looking at the entire rear system. There are 2 of these actuators. The front one controls airflow going either to floor or ceiling vents, the rear one (towards middle of entire unit) controls AC vs heat percentage flowing through the ducts. Unplug the connector, and 3 screws to remove it.
Install is the reverse.

No they do go but not by changing the battery its just whats known in the trade as the dominio effect ,us mechanics are used to it this is where you change one thing and something else down the line goes wrong and the poor old mechanic gets the blame ,I think its just coincidence that the actuator valve has decided to go at the same time as changing the battery ,Dominio effect no doubt you will change the valve and then you will get two punctures at the same time .
