Sounds like a bad controller on the dash. The thing with the knobs and buttons. Try getting the unit from a junk yard.

I have the same problem on 2004 Toyota Sienna. The difference is that the driver side does not heat up, but passenger side is heated in the winter. In the Summer, it is the opposite. The air condition doesn't work (hot air) on the driver side, but works with the passenger side. It seems that the back follows the driver side.
