2004 Toyota Matrix Question: air conditioner leaks water
The heater box is on the passenger side of the dash. Open the passenger door, kneeling in the passenger door opening look with a flash light at the bottom of the heater box there is usually a little black rubber hose that allows water caused by condensation on the evaporator to drain out into the engine compartment at the firewall. I suspect a passenger has inadvertently knocked of the hose from its attachment at the fire wall or heater box. - patrick mannion

I had the same problem of water soaking the floorpans on the passenger side. I had suspected it might be an air conditioner leak and the posts I read here confirmed my suspicions. A quick check showed your predictions to be true - the hose had been knocked off the heater box drain. Looks like it will happen again, given the exposed nature of the hose, but I now know it's a 30 second fix. Thanks for the posts. - Visitor
Heavy rain yesterday produced 2 gallons of water in the passenger front and back wells. We loosened the carpet on the front passenger side and used a hose to attempt to locate water entry point. ...
