Step 1: Lift the Wiper Arms

Carefully lift the wiper arms away from the windshield. Avoid touching the rubber blades to prevent damage or oil transfer from your hands.

Step 2: Locate the Adjustment Points

Identify the points where the wiper blades attach to the wiper arms. These are typically plastic or metal tabs that rotate or slide to adjust the angle or height of the blades.

Step 3: Adjust the Angle

Rotate or slide the tabs to adjust the angle of the wiper blades. The optimal angle is typically 45-55 degrees for most vehicles. Ensure that the blades are angled correctly to wipe across the entire windshield surface.

Step 4: Adjust the Height

Adjust the tabs to raise or lower the wiper blades on the windshield. The proper height allows the blades to make even contact with the windshield without rubbing against the rubber seals.

Step 5: Tighten the Tabs

Once the desired adjustment is achieved, firmly tighten the adjustment tabs to secure the wiper blades in place.
