this is kinda funny cuz i just did it yesterday. the trick i used is first i would lift the wiper up and have it off the window(like pivoted) then i would put it back down , and i would try that a few times. that worked on my driver's side one. as for the passenger side i tried this and it didnt work. so what i did was took a screwdriver and a hammer and put the screwdriver head on where the washer would be, and i gave it a few lite taps, i hit it at 4 seperate points and then i wiggled it a lil bit and wallla your should have your wiper. and if you are wondering if hitting it did any damage. not realy out of the 4 times i hit it i got one lil line and after i painted them it went away , plus they have that lil cap to hide that . i hope this helped
