Wiper seals

Got the same problem when the car is sitting on a incline (nose up) and it rains real hard. I have new wiper seals so don't think thats it and car has no rust and cleaned the cowl area real good before painting the car. Guess I'm going to have to set the car out next rain storm and lay under the dash and follow the leak or have some one run the hose on it while I look.
