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...
