cowl area

The drains are at either end of the cowl area between the hood and the windshield. They are hidden by the fenders. They usually get clogged by leaves and junk that get in thru the cowl vents and the water gets trapped in the cowl area.
Removing the fenders is the easiest way to get to them. Major pain in the butt.

Sometimes the water gets in thru the wiper shafts or around the windshield gasket but that water won't get into the cowl area.
