<!-- from fixya rte -->Water leaking on passenger side carpet - Subaru 2012 Outback 2.5i

Sounds like your windshield is leaking take it to safe-light they will take a look and make recomendations

Blocked A/C drain or leaking heater core. Are you going through coolant?

Your heater core has developed a leak - the wetness on the passenger side carpet is engine coolant
from a heater core leak, or a leak in one of the two hoses connected to the back of the heater core.
Your strategy: disassemble dash down to heater core, determine whether you'll need a new heater
core or new hose (or new hose clamp), then replace the offending part.

there is a leak because the foam has disintegrated, or the seal has broken open down by where the feet of the passenger is. Rust stains tell me that the leak may be caused by a break in the body somewhere.

Try spraying expanding foam in the area between the plastic and the metal parts to try to seal out moisture from coming into the passenger compartment.

air conditioner/heater compressor's or evap canister is leaking on the floor. It is very common with the focus. After time that water begins to stink! Try silicone to seal the leaky component which would be above the floor mat.

passengers side carpet sounds like a broken {{ heater-core }} although im not actually there to see oit best way to determine this is to first 2 people one inside the vehicle the other with a garden hose and look for the leak 2nd alternative open your radiator cap and see how much fluid is lost run the heater full there can be also seen running down from inside the passengers side where the heater core is located it will most definitively be 1 of them .

I think that I can help you. It sounds like your drain-tube is plugged up. Get in the passenger side, and pull the carpet back from under the glove box. Look for a black rubber pipe that goes from a black box, and pokes thru the firewall, on the passenger side. Remove the hose from the box, and have a container ready to catch water. If water comes out of the black box, your drain hose is plugged up. Clean out the clog, and you will be golden.

It is definately your AC water outlet. The hose must have shifted sort of.

Hi, we also have a 2002 Toyota Rav4 and developed a leak in the front driver's side of the car. After much research, we discovered that the drain wells from our sun/moon roof were clogged. If you have one of these, I suggest that you open the sun roof and look carefully. You will notice some tiny little holes in front and in the rear of the sun/moon roof tracks. Over time, these become clogged with dust and debris. You need to find a long, sturdy piece of thin wire and run it down the holes. To test if you have properly unclogged these, take a small amount of water and pour it down the holes. You should see water coming out of the drain wells under the car around the rear of the front tires. Hope this helps.

I am the original owner of camry xle 1998 with wet floors. In 2000 I had drivers side door seal leaking at welt. Removed old door seal and new weather strip on drivers side installed. The door panel was never wet, but wet at bottom of door where there are drain holes...slowly leaking under carpet.
In 2001 later water again. Coming from overflowing A/C evaporator-drain plugged/ tank full of debris. Removed evaporator, cleaned + drain cleaned.
In 2003, driver door seal against window rotted. Removed door panel and found leak at window belt molding at the mirror joint inside + out. Lots of mold under carpet needed to replace! Made a fuss at dealers for reacurring problem and they replaced the carpet for free.
