1999 Dodge Caravan Wet Carpet

The carpet backing on my wife’s 1999 Dodge Grand Caravan is soaked and now that the weather has started to warm up it’s developed a mildew smell.



It’s still cool enough out that we haven’t been using the AC very much so I don’t think it’s the cause. But just to be sure I checked the hose under the car from the condenser and it seems clear.



After pealing back the carpet I poured water from the roof over the windshield and don’t see any water entering the car, it drains out the cowl hoses.



It’s on both the passenger and driver side.



Any suggestions where to look next?



Thanks in advance!

Tom
