Peter,

Thanks for the reply. I checked the sunroof drains after successfully disassembling the motor and rebuilding it, and thus getting my sunroof to operate. I ran a coat hanger through the drains and then poured water in them to assure that they all drained properly...which they did. So now what? All that seems to be left are the windshields, and I cannot see any evidence that they are the cause (other than the water pooling in the floorboards!). If the rear glass were leaking, would I not have a damp hat shelf after it rains? If the front were leaking, would I not see it pouring in as I'm driving through a deluge? Perhaps I should do the medical equivalent of an angiogram(?), and pour water with red food coloring in it on the various suspected leak points...

...out of ideas.
