all you have to do is remove wipers and the cowl, take the piece of weather stripping from the factory that is most likely laying above your blower motor, clean the track and rim below the windshield with alcohol or an all purpose cleaner quirt in some all weather adhesive in the mounting track of the original piece of weather stripping and stick it on. Wait a couple hours for the adhesive to set up. Reinstall the cowl and wipers. Problem solved. I do this 3 times a week at least with customer cars for the last 7 years. Not one has came back saying they have water in their floorboard......again. 3 hour fix!
