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.

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.
