Thanks master tech!
I suspected the "best" solution was to replace the heater box. Unfortunately, the dealer quoted me the price of the part woud cost me $329 and the labour to install 7+ hours! Not worth it for me...given the car's currenty value. BTW -- the scantool was able to actuate the motor.
Dodge does not sell the blend door seperately and I would need to buy the entire box.
I was hoping to get some heat for the winter, and might resort to plug in heaters as a stop gap. I was hoping for some creative DIY solutions to my problem. I found a thread on another forum which descirbes nicely a DIY fix, but I am not sure if I can post it here?
It involves cutting the heater box to remove the broken door and fixing the door. I am probably going to go to a local bone yard to find the door intact ... my question is, do all 4th gen caravans with front a/c only and single zone climate control have the same heater box assembly? If so...it helps to widen my search for the elusive part.
