The next step is to remove the end cap. Carefully pry the cap off the stalk with a sharp, flat tool.
Now that the end cap is off, hold the wiper switch still, and unscrew the single Philips screw. Don't slide the switch off yet!
Before you slide the rotating switch cover off, place your hand under the entire assembly as shown. Be careful not to lose the spring-loaded switch detents (top one is circled, the other is on the bottom).
Put a nice dab of the dielectric grease on a Q-tip. Then, apply it liberally to the entire contact surface as shown:
Next, replace the Philips screw while holding the outer barrel in. If the screw is hard to turn, remove it and try to start it in a different position.
Finally, replace the endcap, aft cover on the stalk. Enjoy your exorcised windshield wipers.
