We have a new problem with our 03 vibe. There is tons of condensation inside the car that freezes up, but I have found only one small leak in the back that accounted for about one or two ounces of water.
The seats feel a bit damp, but I can find no leaks in the car. The carpet is dry. I did notice after a hard rain that the two moonroof drain tubes in the back had no water at all in them. Wondering of there is a clog somewhere.
