I am not sure, but it sounds like your heater core may be leaking. You may be lucky, and only have a hose leak. But most of the time its the core that goes bad and needs fixed or replaced. You may check under your hood and look at the two hoses that go into the fire wall on the right side of the car. If your lucky one may be leaking at the clamp and only need to replace that clamp. But most of the time it will be the heater core in the fire wall that's the problem and need's replaced or fixed. If you need to drive the car before getting it fixed. You can take both the hose's off the core at the fire wall. And connect them both together with a two or three inch pipe and two clamps. This way you can still drive your car until you get time to have it fixed. Be ware though that by placing both hoses together you will not have a heater. Good Luck M.C.S.

Passenger's side? Could be a leaking heater core
I BELIEVE THE WATER COULD BE COMING FROM YOUR AIR CONDITIONING .
It could possibly be the heater core Check your heatting and a/c
The most likely culprit is the heater core.. its usually located under the dash on the passenger side.. if it starts leaking you will have water on the passenger side floorboard.. also the radiator fluid will be low.. Another possibility is the drain from the ac is clogged... alowing condenced water from the ac process to dump in the passenger side floorboard.. the heater core and the ac drain are located in the same area...
Passenger side floor? Could be leaking heater core
definatly the heater core
It could be the coolant overflow tank that is leaking.
Possible, but more likely a leaking oil filter or valve cover
Perhaps slave cylinder, line or fitting leaking?
you could have a heater core leaking or your windshield is leaking and the water is running down behind the dash and onto the floor.
If it's air conditioned, the condensate drain could have become blocked and spill over into the floorboard.
drain for the air conditioner heater case could be stopped up,or a heater core leaking... !!!!
