2006 Silverado Windshield Wiper Arm Spray Problem
 

I'm hoping someone can share their expertise to help me. The driver side wiper is not spraying out washer fluid. I can't get this piece to stay in the hole and I'm wondering if it's the issue. Did I break it? Looks to me like the driver side wiper has two spray points on the wiper arm and this is the "bottom" one? So what happens is a bunch of fluid just leaks out of it while I turn it on (the passenger side's spraying is perfectly fine). Does anyone know if this piece being out of the hole is the issue? I can't get it to stay in there so I have no idea what the hell is going on. Any help would be appreciated. Thanks.
