Cant remove old wiper blades on cutlass Oldsmobile?

With older vehicles you may have to use some WD-40 to loosen corrosion first. Be sure to not bend the wiper arms but you may have to use some torque in the right direction. Soak it good if its corroded.

The 1975-1984 Oldsmobile Cutlass has "3/16" side lock" wiper arm attachments and the 1997-1999 Oldsmobile Cutlass has the most common hook-end wiper arms. See Sources and Related Links below for installation videos. Also, purchase the replacement blades first and there will be additional instructions/illustrations on the replacement packages. Its very easy.
