Was there a 1984 Oldsmobile Cutlass Calais? I see them listed at 1988-1991. Assuming that you mean "wiper blade" (blade and frame) which are replaced often rather than "wiper arm" (piece from the spindle at the hood to the wiper blade) which are rarely ever replaced, ALL 1988-1991 Oldsmobile Cutlass Calais' have 3/16" Side Lock wiper arm attachments.

Remove the wiper arm from your 1999 Oldsmobile Cutlass wiper motor. Remove the wiper motor wiring harness. Remove the wiper motor retaining bolts. Reverse the process to install the new wiper motor.
Check either at the bottom of the windshield washer fluid reservoir or check to see if the wiper motor has washer hoses connected to it
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.

The 1996 Oldsmobile Cutlass Supreme 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. Locate and press the tab or button where the wiper blade is inserted into the hook of the wiper arm and pull wiper blade out of hook. You may have to rotate and flex the blade to make enough clearance for the hook to pass through.

The 1984 Oldsmobile Cutlass Supreme takes 18" replacement windshield wiper blades on both sides front. Note, when buying wipers be sure to always lookup your vehicle make, model and year in the application guide book at the store, or now-a-days you can Google 'lookup wiper size'. You want to look this up because correct wiper fit is more than correct length, it's also proper attachment. Not all attachments fit all arms. Using the application guide or looking up wiper size online will avoid headaches of buying the right lengths with the wrong attachments.
All model years of the Oldsmobile Alero have hook-end wiper arms. See sources and related links below for installation videos.
