Mildew smell coming out of HVAC. The passenger vents also blow cold are when the heater is on. I'm not sure where the smell is coming from, but the smell is similar to an electric smell I had in the truck when my alternator started to go bad at 70K miles.

When the '2004 Dodge Durango sits for over a day or two in the summertime my vehicle sometimes smells like vomit and/or cat urine and the smell does come from the front and rear AC vents!

moldy smell from A/C vents when first turned on after sitting a couple of hours or longer. Changed cabin filter. Did not solve problem!

Air conditioner has a musty or mildew smell. There is no cabin air filter in the 2003 and older dodge durango. I have a 4.7 Liter 4X4 with low miles that drives great but the smell is nasty.
If ac was off and only cold air was blown after a/c on then a musty odor was detected. condenser replaced but now is doing it again. Techs state no further action can be taken. Really disappointed in Durango. Wont buy another.
