Wiper Arm: Testing and Inspection

Wiper Arm Tip Pressure Check

1. Remove the wiper blade from the arm. Refer to Windshield Wiper Blade Replacement (Windshield Wiper Blade Replacement).




2. Attach a scale to the wiper arm tip and measure the force required to lift the wiper arm perpendicular to the windshield to the normal working height of the wiper arm (the height with the blade attached).
The force required should be between 8.3-10.1 newtons (30-36 ounces).
3. Replace the wiper arm if tip pressure is not within specifications. Refer to Windshield Wiper Blade Replacement (Windshield Wiper Blade Replacement).
