Most likely when some one replaced the windshield they did not put the self sealing riviets in that hold the trim on. remove the cover on the side of the windshield and look. if that is not it check the moon roof drain tube runs in the a pillar

SOURCE: Water coming in to front passenger floor when it rains

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.

SOURCE: water leaks on to floor boards when it rains.

Does it just leak when you are driving or does it leak when parked as well? The reason I ask is if it leaks when parked, you can eliminate a floor pan leak, or a leak that gets water from the wheel slinging it up in the wheel well. These things can be a pain in the *** to find. If it is not obvious, like torn, worn or out of place weather stripping, then I usually take a pressurized hose to wet only one section at a time and narrow down the source of the leak. It could be the seal around your windshield, stripping around the door, or even water getting inside your door and somehow finding its way to floor by draining along the inside door panel. Good Luck! I hope you find this to be very helpful!

SOURCE: convertible leaks

Look for a plugged drain at both rear side panels. Water from the top can enter the car, but it is then discharged out thru drains. If the drains are clogged, you will have this problem. Same for any other Toyota convertible.

SOURCE: Front passenger side carpet getting wet

The AC evaporator units have a drain hose that runs through the floor because condensed moisture is a fact of life with AC units. Yours is plugged. You will have to get under the vehicle and look for the hose where it comes out, then take like coat hanger wire and clean it out, It is somewhere in the vicinity of where the passenger foot well meets the fire wall. If you have to raise the vehicle to get under it, make certain you have it safely supported. If you don't have the stuff, drive the passenger side wheels up on a good curb and use some cardboard to slide under.

Water dripping onto passenger side floor from the inside passenger assist handle.


Does your car have a sun (or moon) roof? A leak in a sunroof will sometimes follow the roof over to the door post and down to the floor were the water will accumulate. This can be hard to find sometimes but having one person spraying water on the roof while a second one checks the inside of the vehicle you may be able to pinpoint the leak.
Hope this helps.

Water leaks


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

In my 2000 chevy Impala has a water leaks under dashboard onto passenger floor, only when it rains?


I had the same problem with a 1994 Taurus. Within the front fender was 10 years of pine needles and leaves blocking the drain backing the water up in and over the fire wall and into the front passenger seat floor.
I took a LONG pair of needle nose pliers threw the passenger side door, and was able to remove enough debree. After pulling out out about 5 fist full's of yuck, 1 gallon a water that was stuck some where poured out flushing out the drain. I did the same on the drivers side. After that I had no problems with floods. I hope this helps. If not check your back door weather stripping if you have one. I have heard water leaking behind the passengers seatbelt and onto the floor from under the seat. Got to love Florida's rain season(s)

Water on floor passenger side after it rains and after air has been running 2000 grand prix


Ac hose leak?
leaking heater core?

Hint: it leaks when it RAINS

If it were related to the heater core or the AC drain, it would be leaking when it is not raining also, so those diagnoses are not logical.

The grand prix has a long history of floor leaks from seal failures around the air intake under the windshield cowling, where RAIN water runs in.

drill a hole through the floor as a quick fix ,if it gets in let it out ,then check for the leak ,try under the firewall where the AC drain pipe is ,it could be the same pipe for drain water coming in from air intake vents

03 impala passenge has FLOOR were it come from


pop the hood and take out the plastic shroud on the passenger side at the firewall. there is a rubber weather stripping that will direct the rain water off the wind shield other wise the rain will fall directly onto the top of the fan motor then run down onto the carpet. i noticed mine when the fan motor iced up and was about an inch thick of ice. all i did was RTV on the weather stripping to redirect the water good luck.
