| the heck. I had my washer bottle out and cleaned it out as good as possible given its myriad of baffles. After the reinstallation, I tested the system out to make sure that it was spraying fine and the connections weren't leaking. Spraying fine it was not. The nozzles were plugged quite a bit. So I disconnected the nozzle hoses at the Y connector above the battery and purged the remaining crud out of the system by pumping about a quart of water through it. After connecting the nozzles again, the spray was still not OK. And probing the nozzle holes with a stiff wire a couple times and respraying resulted in no improvement. I disconnected the nozzle hoses at the Y connector again and attached a blow gun, with a tapered rubber tip, to my air compressor hose. 
With the tip to each hose, I shot a couple air blasts of moderate pressure. Retested the nozzles and they worked perfectly. And BTW, FWIW, when the washer bottle dipstick reads empty, there is really about a quart of fluid left. The WB is '+' shaped and the dipstick reaches only to the bottom of the horizontal portion of the +. Total WB capacity is about 3 quarts.
