Rear Door seal water leak
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.
