b1443 Prius 2018 Base Model

Hello everyone. Im facing a issues with my ac system. The ac gets cold and hot without problem however the driver side vents doesnt work. Doesnt matter in what setting it is, always blows from the bottom, front and passenger. Sometimes stop working on the passenger and only blows in front and bottom (defrost). I ran a diagnostic with my scanner and showed that code. It seems that the problem is the ac servo motor located on the driver side. My question is: Where I can find the part number and maybe a service guide to see if attempt to do i lt myself. There a few youtube videos with other models but I dont know if the same process. Thanks
