Sunroof leaks
SOURCE: 2002 Toyota Sienna Sunroof
There are 4 drains on the sunroof (2 in each front corner, 2 in each rear corner).
If you want to check to see if they are clear, you can do this.
Get a squeeze bulb (about the size of a turkey baster) and squirt water down each drain, look for water draining out at the bottom of the car. For the rear drains, park the car on a slight uphill, and gently squeeze water down the drain trough on each side, here again, look for water draining out of the car.
If those ar clear, next step is to check the seal of the glass. The drains are only designed to take in a small amount of water, if there is too big of a gap between the panel and the body, it will over run the drain troughs (kind of like when the gutters on a house get stuff in them).
Finding water leaks is kind of a pain, but not if you take it a step at a time.
One thing to remember, water does not run uphill.
So to further water test it. Find a place where you can park it uphill or downhill, grab a flashlight, a friend and a hose.
Start at a low spot, and work your way around the sunroof (one person inside with the light, one outside with the hose). Just let the water run slowly, you don't want to use a nozzle or a spray.
Once you can see when the water starts leaking on the inside, you can narrow down the cause.

The drain hoses get clogged behind the kick panels. Pull back the kick panel and reach in grab the hose and pull it out from the hole in the lower panel. Then I just cut off the end and watch the mud and water flow out then reinstall. There is also one in the rear wheel wells as well for the back drains.
There is no reason to remove the headliner unless its broke.

do you have a sun roof, if so start there, because there are two hoses at the back corners of the roof pan that allow water to drain, if they leak, they will soak the rear floorboards, and if not that check the door jam seals.(note that if the plugs on the floor are missing that will be verry hard not to have wet carpet)........let me know?

The ramp up mechinism is not closeing the gasket up tight agaisnt the sealing surface so this is a warrenty issue, take it in and have it repaired by the dealer. If you want asstanice to do it yourself please Post here for detailed instructions on doing it yourself. You would do better in a chat because of the problems you may run into that way you work with just one person. Hope this helps.
