Intermittent wiper problem on '04 V6

got a buddy with an 03 v6 convertible in the yard for parts, msg me if gem and i'll see what he needs in case you need 1 2 or all, prolly get wiper mtr , MFS, and gem pkg deal or single if needed. sounds like maybe those wonderful plastic gears or maybe motor loosened up,orrrrr linkage. I'd eyeball it while someone else operates to dismiss the easy fixes you may be able to put a finger on moving parts and feel stripped gear rasp, or the wobble of loose components, or they may pop right into place
