What about when air only comes out through the defrost vents? Air is still cold air but no other selections will change where the air comes out? All selections will come out from the defrost?? Still enough to cool the cab but not as fast as the forward vents. What does this sound like?

This happened to my truck and it was one of the vacuum lines right by the fuel filter. I had accidentaly knocked it off when changing the fuel filter.

anyways.....



So yesterday when I got home i stuck my head under there and messed with the accuator a little bit. I pulled the vac. line off and there was plenty of vac. I put the line back on and turned the knob to dash vents and saw the arm try to pull a tiny bit. So I helped it through about 3/4 of its swing and it finaly slamed the "door" the other way and then I had my dash vents back. So Im assuming that the diaphram (sp) has a small hole in it or something like that, and its not strong enough to pull the door by its self.



Anyone have a part number for this piece?







Again thanks for all your help guys. This problem was really starting to bug me.

Like vacuum lines that may have been disturbed when, say you're messing with a Pacbrake that keeps getting stuck?

CNichols, the Actuator P/N is 04720279. This is the Dodge number.

i am on my third one in 2 years... . and after last time they told me to only change controls with fan off or on low... so i did it with it turned off. here it is 6 months later and broke again and this time we were riding to lunch and couple miles down the road it pops all on its own... . vent set to panel/floor and fan set to lowest position.



if it happens one more time I am going to trade this ***** in as when the warranty runs out I am not going to pay $500 for them to spend a day to fix a $2 part..... why doesnt Dodge or Geno or someone make a door that wont break? PLEASE... I love the cummins... I love my truck... . but in 25 years and multiple trucks, SUVs, Jeeps, and cars... I have NEVER ever broke even ONE VENTILATION blend door or vent door. Three in two years is a bit much...
