Sounds like a plumbing issue or a leak. On my 15 there is a coil that runs through the washer fluid reservoir that I assume is filled with coolant that heats up the washer fluid to melt ice in the window, I would look at that plumbing in and out of the washer fluid holder as that is where it is most likely entering from.

Superpop, do you know the location of the plumbing because there is no leak from anywhere in the car
