Mine does not. There are blend motors behind the dash that GO BAD. I need to do mine for the a/c. My 2011 has 4 blend motors, I would bet one of yours is bad. This not a repair that should be entered into lightly. IMO. Probably to much time has passed for warranty repair. I would find a new dealer, they only get to lie to me once. The morons that sold me my truck lied twice during the same visit. I found another dealer and begrudgingly go there when it is necessary.
