    bought used 99 gs300 1yr ago. at first it randomnly made soft bubbling/flickering noise under dash on driverside. haven't heard noise in long time. Now the carpet under the mat is damp, but its just on the bottom. No dampness on the sides or front of floor board, cant figure it out. Its been going on for about 1month now.

It may be due to the air conditioning hose being blocked. Therefore the water must be backing up into the vehicle, under the carpets and into the back seats instead of flowing out

It might be some windshield drains that are clogged. the windshield can be fine and even newly sealed , but still the water off the windshield has to flow into the vent in front of the windshield, as it is supposed to. There is a long plastic/rubber tray under your windshield wipers, it acts like a funnel and the water drains from that, through some kind of drains. If these get clogged I think the water drips onto floor. I would search out the drains and try to unclog them, and also get rubber floor mats which can hold some water. Of course do everything to dry out the carpet if it has gotten wet, that is the first thing to do.

Standing water on drivers side floor


check drain holes in the bottom of the drivers side door. If they are clogged the water will build up and drain from the sides and on the floor. Also check the gaskets around the bottom of the door.. You may have to get on the ground and look up to check them... something that people seldom pay attention to.

Sounds like the windshield is leaking. Run water over the windshield and have someone get inside car and look for the leak. Alternatively take it to a reputable windshield repair shop and have them check it.

Water leak after rain, rear floorboards soaked? HELP!


a couple things to look at if it has a sunroof the sun roof would have drain hoses that run down in each corner next you need to look at the cowl this is the section in front of the windshield that has a drain on it as well if you find nothing there the next step would be to remove the seats and carpet and sit in the car while running water over it either way you should remove the carpet and make sure it is dry all the way threw or mold will start to grow and you will never get ride of it not good for your heath other key spots to look at is if the windshield was ever replaced it could be a poor seal

Keep find water on driver side floor and behind driver seat


Do you have a sun roof ? if yes make sure water is not leaking from there, BUT if you don't have a sunroof then have a look under the car's body, there might be some rusty area of a hole under the body letting the water from the road to get in.

Since I purchased my 2000 GMC Yukon XL 1500 we have had a water leak that soaks the drivers side floor and passenger floor behind the drivers seat. I took it to my GMC dealer and they had it two days and...


You may be right about the sun roof. It should have 4 tubes to drain water that comes in around the glass. Sometimes the tubes fall off letting the water come into the cabin. The horn may be the part in the wheel. Apply it at different angles and it might start working. Sometimes they get rusty. I think your cabin filter would be under the hood near the firewall on the passenger side with a plastic cover.

2002 Toyota RAV4 passenger side floor Water


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.

There is a water leak somewhere in my 98 toyota camry that leaks into my passenger side floor. There is no sun roof and no visible leaks from the windows or doors. Any thoughts? A/C leak maybe? water...


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.
