Temperature blend door actuators have been an issue for years-both my '05 + '06 Silverados. In reading up on the issues, it had been an issue for years. Some folks have had success with the battery, like here, others have had to change out the actuators, like me. I would have thought it was resolved...guess not!

Had that warning on for 11 years on my '06 Silverado. Into the dealer at least 4 times-said corroded ground wire. Never did get it fixed long term. Waranty was up quick with my mileage at that time. Warning is still on, but truck still performs as it should, but is slow to engage 4WD and must shut off truck to disengage 4WDwhen it's in the Autotrack mode. My 2015 is good and my 2017 HD is good too, fingers crossed!!
