I had no heat in my 2008 Ranger; the blend door actuator wasn't moving. This blend door actuator video was spot on. It helped me remove the actuator. Turns out the actuator is easy to take apart. When I saw the gears weren't stripped, I cleaned up the grease on the inside (it may have been blocking an electrical connection) and sanded the worm gear motor connectors. When I connected the module before reinstalling, it turned like it was supposed to. Although the space was tight, I was able to reinstall it and now I have heat again at no cost. Thanks for the video.
