Blend Door Actuator - where is it?

[DavisJr]

I am having this issue with a 2009 Yukon Denali.. I have hot air blowing out of the driver's side air ducts when the A/C is on. As stated above, I can not find any additional information about this. Do anyone have any information where I can find these two actuator and some information on steps to change them out?

Any help would be appreciated....

It's the one on pass. Foot. Auto Zone has it. Lifetime guarantee. Costs about 20 dollars. Not too hard to install.

my 09 denali is blowing cold a/c but only on the floor. It will not come out any other vents no matter what the setting is. Anyone know whats causing this?
