If the heater is on and no heat is felt from the right side dash vents, there may be a problem with the blend air door shaft; a revised part is available to address this concern.Google+

I bought this van in Florida so it had never really been an issue till now. I have moved back to Minnesota and would like heat. I have heat on the passenger side and in the back. Not on the driver side. I will be looking at the air temp control blend door as I have read this is the cause on multiple forums.

Blows cold air from floor vent on passenger side of vehicle. Air always blows from floor vent, no matter what setting heat is on. Heat comes out of every other vent on the passenger side - reason is a mystery:(
mines on the left side, wont heat but blows air. right side is fine.
