Ok, I am replacing my windshield arms. The clips to remove them are broken off, so I can not get them off in the normal manner. Well the clips are sill there, but do not hold the wiper out. Do those clips also "disengage/unlock" the arms from the spline? Or do they just hold the wiper arms out so they do "unlock"? I have tried to hold the arms out and pull them off, but it didnt come off? Any ideas, maybe try channel locks, or vice grips? I dont care about the old arms, I have newer ones.
