I have a 2003 Dodge Ram 2500 with the cummins diesel engine. With the air conditioning system off, but the ventilation (heat or just cool outside air) on, I have diesel exhaust fumes entering the cab of the vehicle when idling or moving at very slow speeds. The condition goes away with the a/c on or with the vents in the "recirculate" position - I. E. Not drawing outside air in. The smell and gasses are dangerous for any extended period of time and could cause an accident if I breathe them for a long period of time and then attempt to drive.
