In my truck I have a dual climate control air system. I am trying to figure out why it blows cold on the driver side and hot on the passenger side. Coming out of the defrost vents on the dash it feel like the right side is cold, the middle is warm and the left is cold.  

I took the control unit out of the dashboard and it has 2 multi wire connectors that plug into it. I also went through the manual and checked every fuse that I thought could remotely be related and was not able to find anything.

If this does not make sense I appologize. I am not the most car literate person, but know enough to change my oil and get myself into trouble.

Any help would be great!
