Underneath the right of of the vehicle,straight down even with the firewall that the heating unit is attached too, there should be a small rubber hose facing down. This hose is the drain and is most likely clogged with debris,and not allowing the water to drain properly. Usually you can use air pressure to blown air up into the hose and loosen the blockage.

WET CARPET ON DRIVER'S SIDE


Could be the drain for the ac is plugged up. Usually when this happens the passenger side floor gets wet, but it could be coming out on the driver's side when you take a right turn.
The drain should be on the bottom of the firewall near the floor, you should see water dripping onto the ground when the ac is on.

WATER IS LEAKING INTO RIGHT FRONT FLOOR


I had the same problem on my 98 Century. Turned out when I had my oil changed, they dislodged a rubber "gasket" ( a foot long piece of rubber ) mounted on the firewall seam right in front of the passenger compartment air filter box under the passenger side windsheld wiper. It diverts water from the windshield so it doesn't flow into the fan blower box and onto the floor. It's a crappy design. If it's not in place all the water runs into the car. I had two inches of water on the floor, had to pull up and wring out the soundproofing, hit it with a hair dryer ( took two days to dry ), same for the rug. Put some silicone in the slot on the bottom of the rubber piece and set it on the firewall seam. You should see where it was originally. Good luck.

Water drips onto carpet on passengers side front foot area. Can be seen dripping from plastic air ducting above foot area. how to figure out how its getting in. Have replaced windshield.


You can only have 2 issues dripping water onto the passenger floor board. First being a clogged drip line for the ac evaporator. The other is a leaking heater core. Figuring out which one is the issue is fairly easy.

If your vehicle has anti freeze in it when you turn the defrosters on it will smell sweet. If it does you have a leaking heater core. If it does not then the drip line is clogged.

To clear the drip line get under the vehicle and snake the drip line on the firewall. It usually is a 90 degree rubber or plastic piece on the passenger side about a third of the way up the firewall. A leaking heater core means it has to be replaced and not really a job for someone that is not exsperienced.

My 2004 Dodge Stratus SXT has water under the front passenger seat and pools up in the rear passanger floor. I thought it was rain filling up in my rear passanger door because that has happened before, but...


You most likely have a plugged a/c evaporator drain tube. This tube drains away the water that condenses on the evaporator core [the one under the dash next to the heater core] whenever the a/c is running. If the tube is plugged then the water will fill up the bottom of the plastic heater/air conditioner housing until it overflows and leaks onto the floor. This drain is located on the engine side of the firewall, passenger side, down very low at the bottom curve of the firewall and is usually a very short rubber hose about 2" long. It can be hard to spot as there is often a lot of stuff in the way that makes it hard to see. A quick check is to park the car on a level spot and operate the a/c for sevreral minutes. You should soon see water dripping onto the ground from under the car on the passenger side of the vehicle. If you see it dripping then the hose is ok and you have a different issue, if not then you can pretty much bet that the hose is plugged. I usually use a puff of air to blow out whatever has plugged the hose [bugs, debris, etc] which fixes it until the next time it plugs.

Water sloshing around in the vent, leaking onto passenge floor.


There should also be a drain tube or hole below duct work on outside of firewall or maybe even lower.

Water leaking onto floor of front passenger side of vehicle


Water on the floor indicates a heater core leak. You may also find a mist coming from the inside of the car when you run the heat and or AC. If this is the case, have your heater core checked out. Best of luck.

Fluid leaking onto the front passenger side floorboards.


2004 TB 60,000 miles. i was just told that the leaking fluid in my passenger side floorboard was do to a clogged up A/c hose. An A/C works by drying/ removing the moisture from the air inside the vehicle and cooling it. The accumulated fluid is usually evacuated under the vehicle which is what you see when people are stopped at a red light and there is dripping under their car. when a hose is blocked there is a vent that from some reason flows directly into the passenger side floor board. If you can not manually knock loose the block your probably going to have to take it to a mechanic.

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.
