Water leak, dash- WIpers?

Frirst thing is to try and find the leak. Spray some window cleaner around the outside of windshield. The take an airhose and blow from the inside out, look for bubbles. Little harder to check the wpers but the same method can be used. Just harder to get to the underside of wiper arms. There are 2 different gaskets for the wipers. 1 on the outside just under the cowl metel, which can been seen from the top of car, its blackand bout 3/8" thick. The other is on the unerside of dash, lots of things in the way but can be done, hte foam gasket bout 1/8". Hope this helps. I will look for a pic.
