Blend door to air conditioner

Hi and thanks for using 2CarPros. Com.

They are under the dash and not easy to get to. Here are the directions for accessing and repairing the blend air door. The first two pictures are of the actuators. Keep in mind, there is one for the left and one for the right. These items are located under the dashboard primarily behind the glove box area.

Here are the directions for replacement from alldata. Picture 4 correlates with these directions. This is for the right side control.
