Rear Window Washer Not Working on 2004 QX56

[pads fan]

Anyone know what could be the culprit for the rear window washer not functioning on a 2004 QX56? I can hear the pump trying to pump fluid back there but nothing comes out. Front windshield washer works fine and yes, there is plenty of washer fluid in the resevoir. It's full. I tried sticking a pin in the hole of the washer to unclog any debris but it was not clogged. If I can't figure it out, I will take it to the dealer and bend over for my routine raping.Thanks!Steve
