Hayapower -> RE: 2003 Crown vic wiper motor arm cap removal (9/29/2007 3:49:21 PM)

There isn't a lock nut inside .. They are a 'slip fit' over the pivot shaft splines, with a positioning/locating key.. When you slide/pull the release tab out from the lower portion of the wiper arm, it will release the arm from the pivot shaft.. You may need to push down and/or wiggle the arm as you move the tab out.. Make sure the arm is fully lifted on over center position, (like when you clean the glass and they remain lifted sticking straight up).. So,, raise the arm over center,, then simply/carefully pry the tab out, and gently 'rock' the arm slightly as you pull straight up.. There will be a locating 'key' that should stick to the pivot shaft or may stay inside the wiper arm bore..
