1999 Plymouth Voyager Water from A/C leaking into Car

No doubt you've seen water dripping from an air conditioner as moisture in the air blown over the cooling part, the evaporator, condenses on it. The same thing happens in cars, with the same solution: a tray to collect the water and a drain tube to direct it away, in this case under the car onto the pavement. In your case, this drain tube is clogged with debris. You should be able to see it just behind the engine to the passenger side of center and push a soft wire up through it to get it unclogged.

Thanks for the tip, but it didn't work. It turns out the water leak was coming through the a/c unit from under the hood of the car - it was rainwater! On the Voyager there is a hose which drains this water to the ground; it was clogged with debris. Tricky!
