Ok so after finding out my 2005 Yukon XL had no rear heat and was blowing out only cold air I researched the issue but am coming up with multiple part #'s.
My XL has the over head rear heat controls as well as the rear controls behind the center counsel along with the radio controls. When I removed the rear panel to access the actuators and module I noticed an actuator missing, just it's wire connector hanging there. When I call all my local GMC dealerships to try to find the part number of the actuator missing they try and tell me only the short base (Yukon and Tahoe) have 2 actuators and the long base suburban's and Yukon's only have one which I know is false because the actuator I have labeled as #1 in my first picture controls my floor and celling vents and when I manually turn the knob where the second actuator should be (labeled #3) it changes my air from hot to cold. Also, I have the old style control module (labeled #2) which is part number 21997590. All the posts and videos online call for the replacement part #15832319. The dealership on the other hand is trying to tell me the correct part # is 19260762 which is picture #2. I have NOTHING that even comes close to looking like that part in picture 1.
Can someone please help me make heads or tails of this mess???
