BUT I find it hard to believe that NO ONE has manageed to figure out a way to get a better "fan spray" nozzle for the rear window.
It looks to my eye that a standard "unscrew" with a flatblade driver should remove the nozzle and then it would only be a matter of finding another nozzle that sprays well enought with the weakish pressure (as it is being feed from "up front")...
ANY ONE???
BTW We have over 35K miles on the original wiper blades and I'm just now shopping for replacements -- the PIAA silicone and/or "sporza" still seem to be the way to go: http://store.yahoo.com/ltbmotorsport/piwiblsusp.html

Prob the reason there is no fan spray is because unlike the front where the spray hits the windshield while moving. If there was a spray on the rear majority would be blown away from the rear hatch glass, because of the eddie flow.
