I've got a 2006 T&C Touring Edition, and whenever it sits for a few days, Especially if there's rain, I get a musty/moldy smell in the cabin. It doesn't depend on the Heat/AC running.
It seems to me like there's standing water somewhere accumulating somewhere, and I'm looking for a clue where I should start my search.

Thanks for your help

Still under warranty?

 

out of warrenty by about a month
but it might be worth a try, asking the dealer.
they might be willing to make a good faith attempt...

 

check the floorboards under the carpet on the passenger side under the carpet and insullation...is it wet under there?

 

I've checked the carpet and insulation throughout the cabin, and everything seems dry.

 

Don't rule out the HVAC system too quickly. If the drain is clogged, you could be building up mold. It could also be growing in the evaporator. Have you changed your cabin air filter recently?

 

Don't really see any leaks on this i would just check all the drain hoses on it, espeacially the ones on the cowl.

 

I've had this problem on my 2001 Voyager - was worst when it was raining, or when I used the windscreen washers, so looked like it was water going into the air inlet below the windscreen. I solved the problem by spraying a bacterial spray into the air inlet to kill anything off in there, but I assume that there is something growing, and possibly drain holes are blocked. Can someone tell me where I need to look for the drain holes to clear them out?
