I'm assuming that there is a drain line somewhere that is plugged, but I don't know where any are. If I take out the lower panel on the passengers side and then remove the fan I can get the water to drain out rather quickly, but any time it rains it gets filled up again.

Should I be taking apart the grill under the window looking for some blockage there, or go at it from the bottom of the car looking for a clogged or pinched drain hose? With a good rain sometimes I will drain several quarts of water out of the vents.

I've also had it on the recirculating air setting since I saw the problem and it doesn't seem to make a difference.

Any help or ideas would be greatly appreciated.

okay...have you tried taking it to your dealership? using that thing it has called a warrany?

It's got 51K on it. The warranty waved goodbye a while ago.

Aside from that, I trust my own hands digging into my car far more than some 20 something tech at any stealership.

really depends on the dealership. there are good ones and bad ones. anyway, kudos on putting on 51 k mile on a car that can only be 2 years old at most. knock on wood, i'm at 74k and don't have water coming in through the vents.

I wonder if mine has the same problem. Even after a light rain the car seems a bit musty smelling on the inside. Next time I go to a car wash I'll see if I notice a difference.

Every now and then there was a musty smell, but I couldn't pin why it was happening randomly, but it might have been associated with the rain...
