QX4 Washer Fluid Controls

[Sigmaguy40]

I bought a 2000 QX4 recently and I noticed when I pull back on the wiper control arm to wash the front windshield it sprays fluid on the rear window although the front wipers cycle. Also if I rotate the control to spray the rear window it sprays fluid onto the front but the rear wiper cycles. Otherwise the wipers work just fine. What is going on here? Any help would be greatly appreciated.
