The mode door actuator is located under the dash on the left side of the HVAC box.
If you look below, I attached the directions and pics for replacement specific to this vehicle. I am basing this on a manual temp control system. If the vehicle has automatic temp control, let me know.
The last two pics are the recalibration procedure. One way is with a scan tool and the other is without.
Let me know if this helps or if you have other questions.
See pics below.
