The blower motor in my 2006 2500 cummins has only been working on high for some time now any lower and it would smoke causing a horrible smell. This morning it quit working as it was started and ran for 45mins on low it would when switched to high blow for a second or two and shut off smoking.


The most likely causes would be a faulty blower motor, blower resistor or blower switch. All three could have an associated bad smell (melting plastic). A visual inspection of those parts along with a sniff test should lead you to the cause.

If the blower motor had been working but there was low air flow from the vents or a noise, then a broken fresh air/recirculation  door would be the likely cause. Under the right circumstances a melting plastic smell could also occur.
