We do have a few V10 owners on here, but sounds like your blend door might be stuck, which is not all that uncommon on Dodge's, but not sure that that would shut your truck down. I would start by looking there, but I can check around a little more and see what I can find. In the meantime, have you posted this in the mechanical problems/questions part of the board where someone with a bit more expertise than myself can see it and chime in? Good luck!
do you guys know a lot about dodge V10 trucks, ?
my trucks doesn't blow warm air in to the truck after it's been warmed up for a long time, its cold air all the time even when i put it on hot heat ? what do i do, im new to haveing a truck, and i herad that if something is bothering the vehicle that is will pretty much shut it self down till it gets fixed ?
