Just to jump in as I have seen this before on these SUVs. The rear blend door actuator stops moving to full travel. It is normally a stripped actuator but could be a calibration issue as well. So if the rear system is turned on like Colby suggests, then we should try and recalibrate it and then replace the actuator (or at least remove and inspect to see if it is moving).
Here is a guide that helps with this. Clearly this is a front actuator but the process is the same, just a different location.

Below you will find the process from the manual on how to replace the rear actuator. Plus the process to recalibrate it first. Then if you replace it, you will need to calibrate it again.
Let us know if you have questions on this and what you find. Thanks
