Finally got around to fixing it. Pretty neat little device. It's just a plastic cylinder with a hole cross drilled through it at the single inlet. There is a clearance groove that feeds the split outlets. A thin rubber sleeve goes around the cylinder and covers the holes. When pressurized, the sleeve blows up like a balloon and uncovers the inlet holes, allowing flow to the washers. A snap on plastic housing covers the workings.

I'm guessing that the cold snap this winter caused the washer juice to freeze and opened the snap shut housing, pinching a small hole in the rubber sleeve in the process. I just swapped the one out of the parts car.

Just have to pull the the three lines off, simple? Yes, but they hang on REALLY good and there is NO room to work behind the headlight. If I ever have to replace it, I'm putting new hoses on with about two feet of slack so you can get it out where you can deal with it.
