2012 Suburban Stuck on Defrost & Battery Died? Try This Before Buying AC/Heater Blend Door Actuator

I have a 2012 Suburban. The battery died and then when I turned on the AC it only blew through the defrost vents! After buying the AC Heat Blend Door Actuator I was watching a how yo video and saw a comment saying to try a few steps if the battery died before buying the blend door actuator and it worked!

Looks like this should work for 2007-2014 Chevy Suburban, Tahoe & Silverado
