Basic Troubleshooting Steps
Before seeking professional help, try these simple steps:

- Removing the defective motor.
- Installing the new motor and reconnecting all parts.
- Testing the wipers to ensure proper operation.
When to Seek Professional Help
If troubleshooting does not resolve the issue, or if you are uncomfortable performing repairs, consult a professional mechanic. Electrical issues and linkage repairs can be complex and require specialized tools.
Maintenance Tips to Prevent Future Malfunctions
- Regularly clean the wiper blades and windshield.
- Inspect the wiper system during routine vehicle maintenance.
- Replace blades every 6-12 months or when streaking occurs.
