inside the cowl, above the opening for the inside vent, is a built in evestrough looking affair that directs water to each side of the vent opening. this usually is full of dirt, pine needles, leaf compost etc. I usually remove the vent drain plug from the bottom of the cowl, it is sort of a flap of steel screwed on, then i run the garden hose full blast down from the top opening in front of the windshield. you may end up with some water on the floor inside . you can also stick the hose into the cowl from the interior vent and get it to go towards the bottom to flush that drain hole. if you have never seen the inside of the cowl let me know if you wanr some pics with the innee cowl part removed
