Stuck wiper blades

[Dibbons]

How does one remove the wiper blades from the arms on a 1972 Satellite Sebring Plus? I keep pulling on 'em and pushing the round end of the tab, but nothing moves off the pivot. Stumped for now. Thank you.

Squirt a little wd40 on the pin. The wiper blade pops off the pin. The pin has a groove that the spring clip engages into. Might use a screwdriver in between the arm and the blade to apply pressure...
