I too have had the very same issues. No heat. Had the van on a trip when it was -30F and all the windows were frosted over, and I had no place to stop. Little heat and certainly not enough when you have a long wheel base van. Passengers were wrapped in blankets and freezing. Dealer ordered parts in February and they just came in this week, 7-27-15. Just got a call from the dealer and they said that is the best the heater unit does just slightly warms the heat put out by the front unit. On top of the heat issues, I have had window trim fall off multiple times and replaced by the dealer only to have them fall off again. I have a back seat that rattles constantly and they tell me it is a poor latch problem nothing they can do I need to "slam" the seaty down harder. But why only that seat not all of them????? And it still rattles!!!!! Turning up the heat in the front to supplement the back is not a good option as the driver will get over heated and possibly sleepy while the rear passengers are freezing yet. This needs to get fixed. Did I mention how Loud the rear seat unit is too! Poor Poor design.
