Hi, does not matter what is the temperature setting and which blowing direction (face, foot, or window), it blows cold air only. It has no clicking noise. The driver's side works fine.
I opened up the glove box and saw the blending door actuators seemingly work okay (see the attached video). Please shed light on the possible cause.
Thanks.

Hi,

I watched the video. It does appear to be working. Have you removed it to inspect for any damage?

Thanks for responding. No, I have not taken any actuator out for inspection. Part of the reason is I am not sure which one is responsible for air control for the passenger side. Can you point it out for me?

Hi,

No problem. There are two systems, automatic and manual climate control, but the actuator is the same. Take a look at the two pics below.

Let me know if this helps or if you have other questions. Note that the highlighted component in pic 1 is the location for the passenger side air temp mix door.

Take care,
Joe
