When a/c is on a bad/sickening smell comes out the a/c vents.
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!

I began noticing a musty mildew smell in my vehicle. No matter what i did to try to correct the problem, it kept getting worse. I will seek a solution through dodge!

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.
