Where is the ac blower motor located at in a kia rio . And how do u change it

Hello, working backwards - "how do you change it" - you obtain a workshop manual with instructions and follow them. This forum cannot reprint copyrighted material on how to make repairs. There are places to purchase that information; YouTube sometimes has some folks doing demonstrations but that may not be reliable. As far as where it is located, under the passenger side dash attached to the plenum. Additionally - what testing has been performed to indicate the motor has failed?
