water in passenger floor

I found water getting wet carpet at the passenger floor on my Dodge Grand Caravan 2001, any advice will be appreciated. I am in Texas and rain is not the cause I think must be something related to AC. Thanks.:shakehead

If you haven't had any rain, you're right it is condensation from your air conditioner. The drain is probably clogged. There is a black tube that sticks out of the firewall on the passenger side. You may be able to reach it from the top, but your best bet is from the bottom. You can stick something flexible in there to unclog it. It probably sticks straight out, instead of pointing down. That was a design flaw and the Dodge dealer sells a piece of hose with a 90 degree bend you can stick on it so it points down.

My 96 Voyager 2.4L started fogging the windows and dripping a bit on the carpet after my son started using it in San Francisco, where it is much more humid. I figured must be the heater core, so pulled that out (pretty easy, it comes out by the driver's foot, just unbolt the steering shaft). Water poured out when I opened the cover, but clear, not radiator coolant. As suggested above, I found the drain on the firewall and stuck a wire up it. Water poured out, problem solved. I don't know if the drain was clogged, or it has a float valve that stuck (most have a way to keep engine fumes out). Had a similar issue in my 69 Dart and 82 Aries.
