The place thought it was the wipers so they replaced them. It was the shield, so had to bring it back. Hard to test without having rain, but finally got it all worked out.

Dealership contractor had previously replaced leaking windshield, but did not replace rain sensors in new windshield. Had to make 2 trips to dealership because parts were not on hand, so had to come back on 6/1/2015 to have sensor installed. Of course no one at dealership called me to tell me part had arrived, I had to call them to find out what the delay was, only to find the part had previously arrived.
