It was an older window that did not have holes for the rain water to drain outside. The water would build up during a pretty decent rain storm, and would eventually seep through the bottom of the window, down the wall on the 2nd floor, and out above the sliding door on the first floor. I just pulled the exterior glass pane down to prevent the water from coming in, and the leak stopped. I eventually ended up getting the window replaced 2 years ago and have not had a problem since.
