I got my SSR back from Water Works, again, today. I had to take it back because she was still leaking. They found a few reasons why they leak. One, the area on the passenger side just above the wiper motor is a huge space where they had to fabricate some metal and goop over the top of the motor so that the water would not fall back into it. The other area is in the center of the Cowl directly under the wiper on the drivers side. At this area is a vertical cylinder made of very thin rubber. When it gets cloged up, which is easy to do, the water pools in this area and then when I made sharp left turns after rain or washing the car, the water sloshed over to the area on the passenger side, into that weep hole area, and over top of the wiper motor and under the dash. It ain't pretty, but the plastic cover over the cowl area makes it so you won't see this mess, but the bottom line is it is fixed and under the plastic cover when done. Hope this helps you all with your probs. a bit.
By the way, that little cylinder of rubber can be felt if you reach up under the center of the cowl area by the driver's side wiper where it attaches to the cowl area. If you pour water into where the wiper is, it should drain out that little tube. If it does not, then clean her out man!
They also told me that on certain Fords they have worked on there was a similar problem, only the water got onto a major computer component and the trucks actually started on their own in the rain without a key or anything.....kind of like the book by Steven King, "Christine". They also said there were 45 TSB's on the new Pontiac Solstice regarding leaks.
