15. The molded cowl cover according to claim 1 , wherein
the molded cowl cover is made from a thermoplastic resin.
16. The molded cowl cover according to claim 1 , wherein
the nozzle mounting projection extends linearly from the upper surface to the washer fluid passageway.
17. The molded cowl cover according to claim 1 , wherein
the outer surface of the nozzle mounting projection has an annular shape extending outward from the upper surface.
18. The molded cowl cover according to claim 17 , wherein
the nozzle mounting projection includes an nozzle opening fluidly communicating with the washer fluid passage and co-axially centered with respect to the annular shape of the nozzle mounting projection.
19. The molded cowl cover according to claim 7 , wherein
the nozzle openings extend from respective ones of the nozzle mounting projection and the second nozzle mounting projection to the washer fluid passageway in a direction perpendicular to the washer fluid passageway.
20. The molded cowl cover according to claim 9 , wherein
the inlet opening extends linearly from the lower surface to the washer fluid passageway.
