#20 of 128 2003 Sienna Roof Leak - Pours in through garage door opener panel
Aug 01, 2008 (11:28 am)
Greetings, and HELP!
Just had one heck of a down-pouring of rain, and went in to my van and found water running steadiily out of the Garage Door remote-control button panel in the ceiling, and pouring down into the cup holder of the console between the front two seats. When I moved the van into shelter, water sloshed up within the ceiling somewhere, and even more water gushed out of the panel.
I've never had the problem before (purchased the van new in 2003) whether the van was standing or going 70mph down the highway in a down-pour.
Can anyone help me trouble-shoot this? I''ve called the local Toyota dealer but not gotten a knowledgeable reply - likely need to "open it up".
Any help you can give me will be greatly appreciated!

Ah! My van was hit in the right rear... however the water is collecting in the back trunk area. From what you've seen behind that panel could water also go down instead of forward? Are there any instructions anywhere on how to take the panels off without breaking them?

Well, found it. When they replaced the fender they did not re-insert the drain tube from the a/c system so it was hanging inside the trunk.

Had replaced the windshield several months ago. Seal at top of windshield leaked - possibly due to rapidly cooling the windshield with air conditioned air when starting up on a very hot day.
Resealed the windshield, and the leak is now gone.

Glad to hear both of you sorted those issues out.
#25 of 128 '04 Sienna Interior rear storage area water leak?
Sep 23, 2008 (4:19 pm)
Over the past few weeks I have noticed the rear storage area carpet in my '04 Sienna is wet in areas and there is a small amount of mold now growing in a couple areas. For the life of me I cannot figure out what is leaking. Rear door? Window seals? Have water tested and found nothing so far.
Anyone else had this problem? Suggestions?

Do you have a moonroof?
Also, make sure the drains under the door jambs are clear, so water can drain out from your rocker panels. I think the holes are near the jacking points.

Yes, we have a moon roof but have never noticed a problem with it. The carpet at the liftgate area is the only dampness we have ever noticed in the van which has basically been a great van but I could live without the mold!!!

#29 of 128 Waterleak in the storage area
Dec 30, 2008 (12:13 pm)
I have '04 Sienna LE. We were very happy with the vehicle till 6 months ago. When we first saw water inside the storage area, we thought we spilled it. Then we noticed the water on every small rain. Took the vehicle to the dealer. They said replaced and sealed the o-rings and washers in the hatch. It did not work. They checked the a/c ducting and found nothing. Later they directed us to the body shop. Body shop replaced the hinges and bolts in the rear hatch. It appeared to be solved the problem. Last week rain again broght the water in side.
Body shop wants to check thouroughly and investigate?
Please inform me if you find this problem fixed.
