We started noticing a musty smell coming from our vents. The smell is only present when the vents are on. It is horrible. We took the van to the dealership where we always have it serviced. They want $110 just to see where the problem is. I am not the only one who has this problem, they need to recall the parts that are causing this problem and fix it. I will never buy dodge again. Way to many problems!!!!!! And they fight tooth and nail not to fix their own poorly engineered vehicles!!!!
Same problem, with musty odor, smells like urine when AC is first turned on. Just started this summer 2011. Where is the AC exit pipe??? "REPLACE THE EXIT PIPE AND PUT A SILICON TO DRAIN THE WATER OUT SIDE THE CAR" post a picture please
Musty smell whenever the A/C units starts and from the drivers door when the window is opened.
moldy, musty, un-removable odor
Musty smell coming out of the vents when A/C or heat is turned on.
did not fix it as of yet. but now I know what it is.
We have a 2005 Grand Caravan SE. A musty odor comes out of the air vents when the AC is on. Noticed it start over the last month. Appears that there is no cabin filter so looking for a solution to eliminate the odor.
When turning on the blower, heater or AC, smell coming from the vents was like manure. Took the van to the dealer and they could not find the problem. They put a refresher into the system which lessened the smell, but did not completely eliminate it. It's now wait and see.
Changed cabin filter and used shop vac to suck out vents helped out alot
Every time we get into the van my husband starts sneezing. He has said for years that the vents blow moldy smells.
I havent had a chance to fix it but it gives me a headache as soon as I turn heater onfast and it does not go away it seems to get worse as it gets hotter . Looking to fix it I will let you no
Smell from vents
I just bought the van used. I inspected the car before I bought it and turned on the A/C and heat. There was a slight smell but it wasn't anything I would consider out of the ordinary for a 10-year old used family van. thirty miles into the trip home, the A/C was on and smelled very moldy, similar to an old motel room.
Not fixed yet - but was advised that it's a mold issue and there is a spray you can purchase at an auto parts store and it stops the mold and keeps it from coming back.
ordor happened right after restart operate air conditioner, never fixed, it will all right after running 20 minutes.
