AC only comes out of the driver side

Just getting into this. Cold air on driver side, warm air on the passenger side. Any thoughts?

There is a small electric motor assembly that moves the passenger side damper from heat to AC. Apparently, when the part failed the damper was on the heat position. Removed the part and moved the damper by hand to the AC position. Don't know if I will get a new part or not, will see how the system works as it is. The part is easy to get to by removing the glove compartment, which was a snap. In the winter, i will turn off AC and hit the recirculation mode. Maybe a blanket for the passenger.
