Water in the heater fan??

[240Zdragon72]

I have had a phantom leak in my Zed after it rains or during the night when the dew runs off the car. I could not figure out where it was coming from. Last night before driving to work I turned on the heater fan to defog the windshield. I had water spewing out of the sides and top of the fan assembly. How does water get in there? Can a fix be done to stop the water from entering the fan?

you have a rust through above the blower housing at the base of the vent under the vanence panel that is outside the front window-fairly common.
