3: manually drag the wiper until it ALMOST reaches the point where it will return
4: manually return wiper to start position.
This will make the wiper motor suck oil into itself and soften the leather seal around the piston.

Old Redneck I disconnect the hose at the wiper motor. I squart a few drops of mmo in and use just 5 pounds of air pressure then works the wipers by hand several times. Then install the vacuum hose start the motor and watch the wipers. Should spray water on the windshield. I have done this on several of my early fords that work very well. Make sure the air pressure is no more then 5 pounds. MMO is Marvel Mystery Oil. Some use brake fluid, I was afraid to.

Thanks very much for the instructions runewilliam_merc and Old Redneck. I'll try that on my '61 Mercury. My problem is that I never intentionally drive it in the rain, so the vacuum wipers get a little ignored. Probably the only part of the car that does
. I'll replace the blades while I'm at it.
