2001 Toyota Sienna leaks along the top of the rear Door seal. Leak tested with hatch (door) open and running water along the gasket and water seeps into the back of the Sienna from under the floorboard. I ran a bead of silicon along the gasket and water tested again when it dried - no leak. I thought the purpose of the gasket was to keep rain water out when the door is closed. Is it normal to leak behind the gasket (between the body of the car and the gasket) in through the floor board? Should I replace the gasket or will the silicon be enough?
I have a Sienna 2001.
I've had the wet floor carpets for almost 2 years.
I have checked and rechecked all the doors rubber seals (weather stripping). There isn't a no sunroof.
I almost yanked out all the side plastic boards.
I just found the source of the leak last Sunday.
The High-mounted (3rd) REAR LIGHT (red) above the rear windshield had faulty rubber seals. The seals soaks water and allows water to drip into the inner boot lining. The water this seeps through the boot panel and flows under the carpet in the boot. With heavy rainfall/water it soaks the underlay and gets up the driver and front passenger foot-well.
I couldnt get a repalcement seal on a Sunday, I had to create a "gasket" replacement froma rubber carpet for the light assembly and ensured I screwed it on tight.
I yanked out the upper (inner) plastic of the boot door and the dripping I noticed earlier stopped when I poured water on the light assembly.
I hope this helps.
Yeah my 2001 Sienna rear door seal leaks also.
Test it buy placing a hose without the nozzle on the roof facing the closed door. Turned it full on. Remove trim at bottom of the door ( i also removed all the carpet and seats), while inside with a flashlight you should know within 2-5 minutes.
Mine was bad, unfortunately i can't find another exact seal without going to the dealer $$$. the after market seals/weather striping, are too generic IMO.
I don't think silicon will do it long term, it tends to not stay attached to soft material like rubber... Replacing the seal is a better long term... :(
If silicon is working,I would go with it,silicone last a long time and it's working.

Your A/C drain hose may be plugged. If so, the condensate from the A/C box will leak onto the floor, and eventually soak the rear carpet as well. This is a common issue. It is under the glove box, close to the passenger floor. Remove it and make sure that it is open. Alos, always run the A/C in the RECIRC mode.
Water in the trunk can be from a bad trunk seal or poorly sealed taillamp seams

This would be your Heater core. They are very cheap to purchase but not so easy to put in since you have to drop the underneath of the dashboard out and aslo have to remove the lines from inside the engine compartmnet. The water goes from the radiator through the heater core to produce the heat for your heater. You should check your radiator or overflow bottle and if the water level is low then this is definetly your problem. This is the most logical, however there could but unlikely be a leak from your windshield. The heator core is located exactly where you say the water is coming from. After reading more does this happen more times other then when it is raining?

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.
