My stock nozzles spray a wide, strong pattern all over the windshield. Maybe yours is semi-clogged. Not sure about the JK/JL thing, but I broke mine and just replaced it with a TJ one on Amazon. Worked exactly the same.

Exactly, the TJ's sprayer has dual nozzles so it's clear one of yours is clogged. Likely from hard water deposits.
