3. Install the New Wiper Arm:

   Align the new Dorman 42586 wiper arm with the splined shaft. Ensure the wiper arm is positioned correctly on the windshield (usually resting just above the cowl). Push the wiper arm firmly onto the shaft until it clicks into place, securing the lock tab.

4. Attach Wiper Blade (if separate): If your wiper blade is separate, attach it to the hook-style end of the new wiper arm. Ensure it is securely fastened.
5. Test Functionality: Gently lower the wiper arm onto the windshield. Turn on the vehicle's ignition and test the wiper system to ensure the new arm operates smoothly and clears the windshield effectively. Adjust position if necessary by repeating removal and re-installation.

Operating Instructions

The Dorman 42586 Front Windshield Wiper Arm operates in conjunction with your vehicle's existing wiper motor and controls. Refer to your vehicle's owner's manual for specific instructions on operating the windshield wiper system, including intermittent, low, and high-speed settings, as well as washer fluid activation.

Maintenance

To ensure the longevity and optimal performance of your Dorman 42586 Wiper Arm and the wiper blade:

• Regular Cleaning: Periodically clean the wiper blades and windshield to remove dirt, grime, and debris that can cause streaking or reduce blade life.
• Blade Replacement: Replace wiper blades every 6 to 12 months, or sooner if you notice streaking, chattering, or missed spots. Worn blades can put undue stress on the wiper arm mechanism.
• Winter Care: In snowy or icy conditions, ensure wiper blades are not frozen to the windshield before operation. Clear heavy snow and ice from the windshield manually to prevent damage to the wiper motor and arm.
• Inspect for Damage: Regularly inspect the wiper arm for any signs of bending, corrosion, or loose connections. Address any issues promptly to maintain clear visibility.

Troubleshooting

If you encounter issues with your Dorman 42586 Wiper Arm, consider the following:

• Wiper Arm Not Moving: Check the wiper motor fuse in your vehicle's fuse box. Ensure the wiper arm is securely attached to the splined shaft.
• Wiper Arm Not Clearing Windshield: This is often due to a worn wiper blade. Replace the blade. Also, check if the wiper arm is bent or if the spring tension is weak, preventing proper contact with the windshield.
• Wiper Arm Making Noise: Ensure the wiper blade is clean and not worn. Check for proper installation of the wiper arm and blade.
• Wiper Arm Position Incorrect: If the wiper arm rests too high or too low, carefully remove it and re-install it, ensuring it is correctly aligned on the splined shaft at the desired resting position.
