4. Test Operation:

   • Observe the wiper's movement to ensure it sweeps smoothly across the window without hitting any obstructions or leaving streaks.
   • If the wiper does not operate correctly, recheck the installation steps.

5. Maintenance

Regular maintenance helps prolong the life and effectiveness of your CHXDP Rear Windshield Wiper Blade and Arm.

• Clean Blades Regularly: Use a soft cloth or sponge with windshield washer fluid or mild soap and water to clean the rubber edge of the wiper blade. Remove any dirt, grime, or road film.
• Inspect for Damage: Periodically check the rubber blade for cracks, tears, or hardening. Also, inspect the wiper arm for any signs of bending or corrosion.
• Avoid Dry Wiping: Do not operate wipers on a dry windshield, as this can damage the rubber blade and scratch the glass. Always use windshield washer fluid.
• Clear Debris: Before using wipers, remove any heavy snow, ice, or large debris from the windshield to prevent damage to the blades and motor.
• Seasonal Replacement: For optimal performance, consider replacing wiper blades annually, especially before winter or summer seasons, as extreme temperatures can degrade rubber.

6. Troubleshooting

If you encounter issues with your CHXDP Rear Windshield Wiper Blade and Arm, refer to the following common problems and solutions:

• Streaking:
  • Cause: Dirt or residue on the blade, worn rubber, or improper blade angle.
  • Solution: Clean the blade with a damp cloth. If streaking persists, the blade may be worn and require replacement. Ensure the arm is not bent, affecting blade pressure.
• Chattering or Skipping:
  • Cause: Dry windshield, dirty blade, or incorrect blade angle.
  • Solution: Use plenty of washer fluid. Clean the blade. Check if the wiper arm is bent, causing uneven pressure on the blade.
• Incomplete Wipe (Unswept Areas):
  • Cause: Worn blade, insufficient pressure from the wiper arm, or incorrect arm installation.
  • Solution: Inspect the blade for wear. Check the wiper arm for proper tension and ensure it is securely mounted on the splined shaft.
• Wiper Arm Not Moving:
  • Cause: Loose mounting nut, motor issue, or electrical problem.
  • Solution: Ensure the mounting nut is tightened. If the problem persists, it may indicate a more complex issue requiring professional diagnosis.
