Hello,

The blend door actuators typically fails either the hot or cold setting.

Your vehicle is equipped with two blend door actuator (left and right).
Accessing them does require removing part of the dash.

I have attached the replacement procedure for both.

Please let me know of any questions.
Thank you.

Good morning,

Just to add, when you are finished replacing the actuator, it must be calibrated in order to work properly.

I attached the procedure below for you to follow for it to function correctly.

Let us know if you have any other questions.
