07 Ford Fusion warm air on passenger side

[Citrus Sandblast]

My 2007 Fusion is blowing hot air on the passenger side. The research I'm doing is leading me towards a blend actuator. Does anyone have any experience with this issue? I live in Florida and it's hot. I see two of them under the steering wheel but I have disconnected both and the only thing that has changed is my heat will not work. Air still blows cold on the driver side and warm in the passenger. Any information would be greatly appreciated.
