having a problem with the dual climate control. drivers side cool and passenger side warm to hot no matter where I set the temperature. any ideas of what to check and where?

I had the same problem with my Cutlass. There's a small module under the dash on both side that control a vent vane. The passenger side module may be burned for some reason, but most probably from a seized vane. You can easily replace it with a new one using a 5.5mm socket. The part no. is on a label on the module. I will try to put pics of the part and it's location later this week.
