Adjusting the rear windshield wiper arm is a straightforward process that can improve your visibility during inclement weather. Whether you’re dealing with a misaligned wiper or one that isn’t contacting the glass properly, this guide will walk you through the steps to adjust it effectively.

Why Adjusting the Rear Windshield Wiper Arm is Important

Over time, the rear windshield wiper arm can become misaligned due to wear and tear or after replacing the wiper blade. An improperly aligned wiper can leave streaks, cause noise, or fail to clear the windshield effectively, which can be a safety hazard.

How to Adjust the Rear Windshield Wiper Arm

To adjust the rear windshield wiper arm, follow these simple steps:

1. Gather Necessary Tools: You will need a socket wrench or a screwdriver, depending on your vehicle’s make and model.
2. Access the Wiper Arm: Lift the wiper arm away from the windshield until it locks in a raised position.
3. Inspect the Wiper Arm: Check for any visible damage or wear. Ensure the blade is not worn out and replace it if necessary.
4. Loosen the Nut: Locate the nut at the base of the wiper arm. Use a wrench to loosen it slightly, allowing you to adjust the arm’s position.
5. Align the Wiper Arm: Move the arm to the desired position. It should rest parallel to the bottom edge of the windshield when not in use.
6. Tighten the Nut: Once aligned, tighten the nut securely to hold the arm in place.
7. Test the Wiper: Lower the arm back onto the windshield and test its operation to ensure it clears the glass effectively.
