Rain is leaking into the passenger side floor from under the dash

Question edited for clarity, add maker.
Question moved to model category.

Based on our research the RAV4s with wet floors are usually, but not always, clogged sunroof drains or drain outlets. Other RAV4 owners found that the body trim surrounding their windshield or even the fender panel had degraded and failed, allowing water to seep in during heavy rain.

Don A has an excellent answer, but if you have a sunroof, that is more likely the reason. The pipe runs down between the door pillar and the windshield and there is often a join there which can part. Be careful with compressed air as it can blow joints apart.

Have your windshield gasket checked. When it rains, and if there is a small hole in the gasket, water will travel around the edges and down the inside. It will flow behind the dash and finally onto your floor

Hi,

This is of concern.....especially if no recent rain.

Your vehicle is covered by warranty and should be checked by your local BMW dealership.

If there has not been any rain, but your floor is wet....it's possible your heater radiator core (radiator) under the dash, is leaking.

Seek immediate attention.

Cheers,

Hello,
If you can smell a little bit of a sweet smell from the water on the passenger side floor, or if it has an oily film to it, you may have a leaking heater core.

They usually leak on the passenger side floor, and that might explain why you hear water sloshing around.

If you can run the engine for about 5 minutes and then turn your heater on. Look under the dash in the area where the dash meets the floor board and see if you can see anything leaking.

I hope this helps you.

Question:Are you running your heater? If yes, your heater core is leaking. Its located behind the dash on the passenger side. Sorry to say, change it. You can do this yourself. Just a tight space to work, and hard on your patience.

did you notice the water after a rain? or was it dry?

the weatherstripping around the door may be damaged. inspect for tears, missing sections, detatched sections, use a garden hose and spray aroun the door seal to see if there are any leaks. also spray around the window to see if that's leaking.

are you sure it's water and not engine coolant? the heater core may be leaking. it is located on the passenger side under the dash. is the coolant low?

there may be a hole in the floor

has the ac blower motor been under dash been replaced ? my brother replaced mine but didnt rain for a while so when there was standing water in the floor board didn't even think about it but after a small wreck and in the process of replacing right fender and hood had to take off cowl vent panel so decided to look and see if could find leak and sure enough there is a rubber seal around the hole the blower motor fits in and it was not seated correctly reached down seated no more leak hope this help worth checking any way

You would have a leak. I would take it to a GM dealer. Could be coming from the windshield and leaking by the firewall.

The heater/airconditioner box under the dash has a drain hose to allow condensation to drain when the air conditioner is running. If this hose gets plugged, rain may accumulate in this box also (if it's raining heavily), as it comes in through the fresh air intake.

Look on the engine side of the firewall, probably on the passenger side, for a hose coming through the firewall that is not connected to anything. It is usually short, has a 90 degree bend, and the open end is down. Make sure that the end of this hose is not plugged.
