Hello and welcome. this is pretty simple job on this vehicle. here is the instructions. just a note, don't plug in the electrical connector of the new actuator before it is mounted to the heater a/c case.
the actuator is mounted on the bottom of the a/c case right above the floor hump. you will need to remove the sound insulator under the dash on the passenger side to get to the actuator
Remove the I/P insulator panel
