Our 2009 Sienna LE passenger side and driver side carpet are both soaked - with the passenger side wetter.
This has happened twice already - San Francisco bay area gets rain mostly in winter months.
The first time, I thought it must have been my fault: not closing the window.
But this time, I am pretty sure it is not the window.
-The leak is water, no sweet smell etc. The heater is working.
-We hardly used A/C, heater. Checked A/C drainage pipe from below, it was not blocked.
-There is no moonroof
-Windshield is factory (it is a 2009 model after all)
