After some searches I believe I have determined that my blend door is either stuck or broken. I can get heat from the vent on the left, but none from the center vents. The ac always works fine from all vents, it seems to only happen when heat is needed. Has anyone successfully fixed this issue? Or is this better left to the dealer? My vehicle is a 2006 limited v8. From what I understand their many be several blend doors on that model...thanks for the help.
