Problem with rear wiper washer

[ChuckTu]

I took a look through the archives and couldn't find anybody with the same problem so I'm hoping somebody might be able to help me...

As you are probably familiar with, the rear wiper washer mechanism sprays the washer fluid out of 3 seperate holes into 3 streaks on the rear window...for some reason the lower one and the middle one are working fine, but the one on the end is spraying straight out the end of the nozzle into the air and onto everything surrounding the truck on both sides, but absolutely none on the upper window...I noticed on the other two that there are nozzle looking things sticking out obviously directing the stream of fluid, but I don't see any on the end of mine...

Could somebody take a look and let me know if there is supposed to be a nozzle on the end? If there isn't, how does the 3rd sprayer get it's fluid on the window? I can't figure it out for the life of me...could it be because I recently installed winter blades?

Any help would be greatly appreciated! Thanks...
