- Access the Wiper Mechanism: Depending on your vehicle, you may need to remove the wiper arms, cowl panel, or other trim pieces to gain access to the wiper motor and linkage assembly.

Operating Instructions
The NISSAN Genuine Wiper Pivot Assembly is a mechanical component that facilitates the movement of your vehicle's windshield wipers. Its operation is controlled by the vehicle's wiper motor and stalk switch.
- Ensure wiper blades are in good condition for optimal performance.
- Do not operate wipers on a dry windshield to prevent damage to the blades and pivot mechanism.
- In freezing conditions, ensure wiper blades are not frozen to the windshield before operation.
Maintenance
Regular maintenance helps ensure the longevity and proper function of your wiper system.
- Inspection: Periodically inspect the wiper pivot assembly for any signs of wear, corrosion, or loose connections.
- Cleaning: Keep the area around the wiper pivots clean from debris, leaves, and dirt that could impede movement.
- Lubrication: While the pivot assembly is typically sealed and pre-lubricated, if excessive squeaking or stiffness occurs, consult a professional for appropriate lubrication methods. Avoid applying lubricants that may attract dirt.
- Wiper Blades: Replace wiper blades regularly (typically every 6-12 months) or when they show signs of streaking or chattering. Worn blades can put undue stress on the pivot mechanism.
