We have had tons of issues over the years with our 2011 Yukon denali HVAC control module. Gm and Ac delco have discontinued new modules for the car. All the recent aftermarket mainly Dorman refurbished units do not correctly function for one reason or another. GM has also tried to reflash the program on these units with no luck. This is a great car but is pretty much useless in south Texas during the summer. I was curious if anyone has swapped the auto dual climate units for the knob type? The problem I always have is the unit thinks the evap is freezing so it will not engage the compressor clutch. The HVAC system worked flawless before this module went out and all the refrigerant levels are correct. Has anyone else had this issue or know of a reputable reman besides the Dorman?

I bought mine off of ebay some time ago, you can used or new but will likely still need to be learned to your vin in either case
I am having a hard time finding the thread, but z71mike I think his screen name is did it. he replaced the auto hvac with a manual one. shows the pin outs and all.

HVAC Temperature Sensor?
Recently our 2008 Tahoe dual HVAC system needs the heat controls turned way up (80 degrees) ti get hot air from the system. I am assuming that there is a temperature sensor somewhere in the cabin that might be needing attention or replacement. If that could be the problem, where is it. Any other...

Same here, Ebay.
I did not have to program my replacement module, possibly I just got lucky with the same options.. (On my second used HVAC module)
One option that might affect programming is 3rd row climate controls.. (My first used module had problems controlling the rear)
Ya mine worked out of the box but later discovered the rear would only heat if it was set to 90, at 89 it would just go back to cold, syncing it to the vin fixed it
