96 grand caravan heater blows cold air

[Regina]

I have a 1996 Grand Caravan. The heater is giving me trouble. It has dual controls (slides for driver and passenger). With both on heat, it still blows cold air on the passenger side. It does this no matter what setting you have it on (defrost, feet, vents). It gets fun trying to defrost the window - half will have ice on it and have is crystal clear.
Dodge wants me to bring it in so they can explore it. I know exploratory stuff can get mighty expensive. Any suggestions?

Yup, take it to them. My dad has a intrepid that never blew air on the floor. he took it to chrysler and they replaced a component in the dash under warenty. He now has floor heat. Let them check it out!
