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!!!!

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.

Every time we get into the van my husband starts sneezing. He has said for years that the vents blow moldy smells.
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.

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.
ordor happened right after restart operate air conditioner, never fixed, it will all right after running 20 minutes.
Musky Odor when air condition starts blowing again now after it been taking apart and thought was fix? Costly for sure. Help, help From Harold F.
