i went the super cheap way on this last year, i took all the cowls and wiper off on the pass side, and when i got to the bottom part, that you replace, the liner part that fails, i took doubled up thick plastic bag, cut it to size, and stuffed it up into the grove where the old one was, left in there too, and silicone it, also silicone the weather stripping under the first cowl piece too, no leak in almost a year now.
