They say in the instructions below it's important to stop the wipers when they are straight up and down on the windshield by turning the key off mid cycle.
- Turn the wiper switch on. Turn the ignition switch on until the blades are straight up and then turn ignition off to keep them there.
- Remove the right wiper arm and blade.
