Hi,

It is located under the dash on the left side of the HVAC unit. If you look below at pic 1, I highlighted the actuator and the arrow I highlighted indicates the front of the vehicle.

The remaining pics are the directions for removal and replacement. Once it is installed, you will need to calibrate it. I included those directions as well. You can do it using a scanner or without one. I included both.

Let me know if this helps or if you have other questions.

Take care,

Joe
