93 100csqw: water in driver footwell

[Wayne Dohnal]

I assume your car is the same as my S4 for this problem.  There is another
drain near the firewall you need to check.  Lift the hood and take off the
plastic shroud just in front of the windshield, exposing the heater box.
There's a drain, almost impossible to see, on the passenger side of the
heater box.  Mine was clogged with leaves and needles.  The trapped water
gets into the heating ducts and randomly distributed to any of the 4
footwells.  I guess you could test this first by just dumping water into the
cavity and see if it drains off.  Mine already had water standing in it when
I pulled the shroud.

If I hadn't found out about this in the S-car archives, I'd STILL be
spraying water on the car trying to find the leak, and that was 6 months
ago!
