Hello, I'm Danny.

After replacing the actuator did you perform the actuator re-learn procedure? Here is a tutorial showing how to replace the actuator:

I've attached below instructions on how to perform the re-learn procedures after the repair has been made.Hope this helps and thanks for using 2CarPros.

Hello thank you for the reply. I did the actuator calibration or the re learn procedure but still no heat I heard there was a total of 3 actuators. Could the other be bad?

I think it was the temperature curator or the blend door one it was the driver side, because I heard a clicking noise coming under the dash. But after it was changed the clicking noise stopped but still no heat.

Hello again.

It sounds like you are having a problem with the mode actuator. I've attached a picture below and circled in blue. Is this the actuator you've replaced? Let me know and we'll continue diagnosis. Thanks again for using 2CarPros.

I am pretty sure the guy changed the one on the driver sound because the the one that was clicking. I couldn't tell if the one you circled blue is on the passenger side because I haven't changed any on the passenger side and also what is that actuator called the one one circled in blue?

Hello again,

That is called the mode actuator. That will direct heat/cold air throughout the specific dusts/vents. I've attached below the installation/replacement steps. You will also have to perform the re- calibration procedure that I attached in my prior response. Hope this helps and again thanks for using 2CarPros.
