I think mine has either developed a leak or something it loose but fluid is leaking out, still works but now it is loosing fluid and the annoying CEL with low windshield fluid keeps coming on.
I looked but it looks like the thing is an iceberg with most of the mass down hidden someplace.

 

sidewalkman, you will need to pull off the bumper cover. From there, everything will be easily accessible. Removing the bumper cover takes about 20 minutes or so. Keep in mind that you will need a T25 torx bit to get the bolts off on the under side of the car. There are also two 10mm bolts hidden on the back side of the bumper cover (1 on each side between the side marker light and the wheel well).

If you need any more info, let me know.
