Replying to: siennaallwet (Aug 01, 2008 11:28 am) 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.

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?

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. Thanks

Replying to: timchi1 (Apr 07, 2009 6:18 am) AFTER EXTENSIVE WATER TESTING,WE FOUND LEAK WAS FROM REAR DOOR,THE REAR HATCH DOOR,SO WE REPLACED THE PERIMETER SEAL THAT GOES AROUND THE REAR DOOR,THE TECH WHO REPALCED THE SEAL SAW TOYOTA HAS CHANGED THE DESIGN,SO THEY MUST BE AWARE OF PROBLEM AND LEAKS FROM REAR DOOR. IT WAS HARD TO FIND SINCE WATER POOLED UNDER FRONT FLOOR MATS, SINCE THE WATER WAS RUNNING UNDERNEATH BODY PAN AND TO FRONT OF CAR.THE LAST WEEK WE HAD HEAVY RAINS,AND NO LEAKS,YEAH! GOOD LUCK,HOPE THIS HELPS JOE. |
