your going to need to seal the strip to the cowl to have it not happen again. I usally use ultra black permatex silicon and apply it to the cowl edge, then after it's in place put a thin bead and spread it along the cowl to seal edge. You could also order a new seal from the dealer too...either way you do it make sure to replace the cabin filter too. (They like to grow mold on them after getting wet a few times)
