have a 2007 Honda accord. I no longer get heat on the passenger side. Also the air coming out of the center two vents above the nav are cool as well.

It sounds like it might be a blend door actuator… But I wanted to ask this group to see what they thought. Next to the cabin filter in the glove box is the actuator that I have been told could be the problem. When I turned the heat all the way up and then the temperature all the way down I don’t see the two white arms on the actuator move. Please let me know what your thoughts are. I also see an actuator to the left of that that looks like it mounts to the center consul and I’m not sure if that is the actual one that could be causing the problem.
