How to Replace Heat/Cool Actuator on 2000- 2013 Silvrado or Sierra

In this video, I show how to replace the actuator that controls the heat/cool temperature door on my Silverado. this is the same on 2000 to 2013 Silverado and GMC Sierra.
If the heater control for changing the temperature of air coming into the cab doesn't work this is most likely the problem.

here is the information I copied from Amazon.
The Air Door Actuator controls the temperature of air and recirculation air option on your vehicle's AC system. This part commonly fails on Chevrolet, Chevy, or GMC models leading incorrect air flow or temperatures inside your vehicle. The blend door actuator is easy to replace on your Chevy Silverado, Chevy Tahoe, GMC Sierra. Sometimes called the air heater blend door, this part is an essential part of your Chevy's air conditioner system.
