Thanks Miker,
I checked the drain tubes and they seem to work well. I dumped water along the space in front of the wind flap and the water drained down immediately (right down and out from under the car). It looks like there are calcium deposits (from water) on the inner part of the seal along the glass, but other than that everything else looks fine. Do you know where else the water may be entering/accumulating? I will try a bigger water test with the roof closed as soon as I have some time.

Thanks, many times
Anthony
