Water Leaks in Sienna

[NoRoomAtTheInn]

I know this has been discussed before, but I did not find any practical answer/solution to my problem. Starting about one year ago, my 2000 Sienna developed a 'puddle' on the floor on the front passenger side -- when it rained. Before long the same occurred on the driver's side. This car has the
original windshield. I have had it checked by the dealer and also a windshield
shop (who blew out stuff clogged in the sunroof 'drains'. Help, these leaks are
getting worse, the carpet is always soaked and I am sure this will cause the floor to rot before its time. Thanks, Lisa

Dear Lisa,
I Meet The Same Problem Before But Not" Toyota Car". The Problem Is From The Body Smallest Broken Or Damage/ You Had Better To Check With Your Car Body Then To Fill The Leak To Solve The Problem Forever.

i think he is trying to say that the cowl has broken and needs to be fixed.

I would also check the cabin air intake at the base of the windshield. Have someone hold a water hose over the the fresh air intake while you look under the dash.

Dear Lisa,

I also have a Toyota Sienna 2000 with a sunroof. I have had the same problem with the leak accumulating on the passenger or driver side floor. I have not yet found a solution. Have you found the solution yet? Did blowing out the drain lines work?
