So, I changed my battery about 6 months ago. And I went through all the reset/recycle steps I've seen but my a/c is still blowing through the defrost vents. Every once in a blue moon it may go to the face vents, but then after a minute or two, you can hear the door close and only blows through the defrost vents. I'd like to fix it, but I only want to replace the actual actuator that is doing this. Would you have the part number and installation tips? Also, on separate note, my rear a/c has completely stopped working. Nothing. no air at all. Any thoughts? Thank you for your help. I have a 2006 GMC Yukon XL 1500 - SLT Trim - 5.3L V8 - Flex - Automatic Controls
