2001 Suburban AC Actuators

Need help- AC actuators will not reset. I have replaced all of them along with replacing the head unit once will a DORMAN then a refurbished OEM. All with the same result of the actuators not resetting. I have done the battery, fuse and ignition on/off to no avail. I can make them actuate using a scan tool but they go to far and still will not operate with the head unit. Any help would be much appreciated!

Did you install them or did a shop do the install? Didi you plug in the power and run them before installing them? If so they will not work correctly. Ran into that when changing one out on my 99.

I installed them and did not plug them in until they were installed. What did you end up doing to get it to work correctly?
