Good afternoon all,
My wife has a 2011 Kia Optima, and while I was driving it earlier, I noticed the air flow coming out of the vents was extremely low. I could change the fan speed and hear it ramping up and down, but the flow from the vents didn't change much at all. After driving around for a bit I did notice my feet were getting pretty cold, so it seems like the lower vents are working.
I switched through the different modes (face, face+feet, feet, etc) but the vent flow never got any stronger. after looking around a bit, I believe I may have a bad ac/heat mode/blender actuator. Now, after searching around a good bit, my question comes down to which actuator do I need to replace, and how can I tell?
After looking at this diagram, [diagram] it appears there is the main mode actuator that changes the modes when the buttons are pressed (#20) and then there are actuators on the left and right side (#21) that I assume open and close the floor vents on driver and passenger side. Since I am unable to get the top vents to open fully, I am going to assume it is the mode control actuator that seems to have died, or malfunctions with just the mode set to floor. I have found a cheap OEM part on ebay (~$40) that I think I will replace and see how it goes from there.
Well, while writing this post it appears to be a classic case of rubber ducky debugging, and I think I know what I need to do. I am posting this anyway incase anyone else has been through this and has any insight, or just in case anyone else gets into this situation, and will report back with how it goes.
