09 LTD MAX - Problem with dual climate control - one side hot, one cold

[quicker]

Ok so this driving me nuts. I have a blend door/gate issue that I have not been able to diagnose but this is a new problem.

I have the dual climate control and both sides are set as cold as possible (60 deg F or 16 deg C) and the drivers side blows cold and the passengers side blows HOT no matter what I do.

Any suggestions on what is going on here? See photo for visual.

Thanks

Without more info, I would guess the blend door actuator behind the radio is the culprit. Any clicking noises? If this is the issue Ford will charge you 10 hours labor for the repair, but you can do it in 1.


Part is $37 from Amazon.

You may have a defective HVAC blend door on the passenger side. The drive gear may be worn.

start digging into it and fix both problems while you are in there

thanks guys. Anyone have any good diagrams for what door actuators are under the dash? It seems I have one bad based on your suggestions above that isnt allowing cool air to the passenger side.

Also I have had a problem with the mode since I purchased the truck a couple of years ago. Very little air comes out of vents or defrost (regardless of mode) but always lots on feet.

So I'd like to replace both when I get in there.

Thanks

Thanks guys. Manuporshutup I used that video and replaced that blend door actuator and it seems to be working as it should now.

All good.

I have a question. Did you hear a slight clicking sound. I'm not having a blend program however, I'm hearing a slight clicking sound behind the radio.

In my case I did not hear the clicking. I just started it one day and turned on the AC and the passenger side got very warm

BUT.... when I first bought the truck (used) I did hear the clicking and I believe it was from the other actuator that controls the outputs (floor, defrost, in your face vents). Currently mine doesn't change when I select vents vs floor vs defrost but I'll tackle that one at a later date as its a lot more difficult to swap.

Here is a video on how to tackle the lower blend door replacement:

Mine I believe is the upper. I hear clicking behind the radio. When turning on heat only the driver side gets warm and the passenger side is ice cold.

yep that was same as mine (but in reverse temp wise). The video Manuporshutup posted above explains the process. Its a quick job. I used a dorman brand replacement as thats what my local parts shop carried. Part number 604-252 so far its working great.
