You can try to recalibrate it but sounds like the rear temp door actuator is stuck
I haven’t had to change mine yet but I did have to change the rear temp controls on the back of the center console as it went out and diddnt have air at all in the back
I believe the rear temp door is located on the passenger side of the trunk area but look it up to make sure

It shouldn’t be that hard? I thought you just have to remove the 3rd row seats which pop right out then get the side panel off that goes around the rear passenger window? They come off easily as far as the actuator I don’t know exactly where it is and how hard it is to get to the bolts but the front one was pretty simple to change

sounds about right might have to loosen/remove another screw or two to tilt the case inwards to reach actuator. Not bad at all.
Might try disconnecting battery for a bit to so it will attempt a relearn possibly giving brief control depending on failure type..

took it apart and apparently the part that needs to be replaced is behind the unit which will take much more work then I can do. You pose a risk of bending or breaking the ac lines that come from underneath the truck. I will just do with out it. Thanks fellas!!!!

@FINALTOUCHFRI I been living with the rear AC not working, the front is AC pretty f-ing powerful so just point the 2 vents above the radio towards the back and it will get the job done
what part? if the rear lines under the truck are cold after it has been running for a while then all you likely need is the actuator, this would be the 1st one right after the fan, 2-3 screws and you are back in business. once you have the rear passenger trim panel off you can see the blend door position, the actuator is not cheap if it is a money issue you can set it to cold and unplug the actuator and you are good till winter.
