Default 2006 Trailblazer A/C Vent Issue

Hello fellow members! I am brand new to the forum and Chevys in general. I just sold my 1993 Lexus LS400 for something a bit bigger and just picked up a 2006 Trailblazer LS. I bought it off the second owner who had it for 10 years. Before I even looked at it, he told me he just replaced the battery. He said that the blend doors for the feet, face, and windshield were not operating correctly and were prior to replacing the battery and that it is a common issue and you need to tell the computer to relearn the actuators. Looking it up, he appears to be correct so I followed a couple recommendations to reset it and get the vents blowing right. I live in South Texas and while the A/C feels good on my feet, my upper half needs it more. I have tried pulling the fuses under the seat with the truck off and while it is on and neither have reset it. When I pull the fuses when the truck is running (HVAC B) the face vents get air, but as soon as I replace the fuse it goes back to feet or defrost. This tells me the actuator is not bad, as air will get to the face vents. Any suggestions on getting this fixed. I've got some other things I need to address with the truck to get it up to snuff, but this is my priority so I don't show up to work with cold feet and 95 degree torso!
