How to Fix a Windshield Wiper That Is Not Working

If your windshield wiper is not working, it can be a frustrating and potentially dangerous issue, especially in inclement weather. To fix a malfunctioning windshield wiper, start by diagnosing the problem, which could range from a blown fuse to a faulty motor. This guide will help you troubleshoot and resolve common windshield wiper issues effectively.

What Causes Windshield Wipers to Stop Working?

Several factors can cause windshield wipers to malfunction. Understanding these common causes can help you identify and fix the problem more quickly.

• Blown Fuse: A blown fuse can stop the wipers from receiving power.
• Wiper Motor Failure: The motor may have burned out or become disconnected.
• Wiper Linkage Issues: The linkage that connects the motor to the wipers may be broken or disconnected.
• Electrical Problems: Wiring issues can prevent the wipers from functioning.
• Obstructions: Debris or ice can block the wiper blades, preventing movement.

How to Diagnose the Problem

Before attempting any fixes, it’s essential to diagnose the issue accurately. Here’s a step-by-step guide:

1. Check the Fuse: Locate your vehicle’s fuse box and find the fuse for the windshield wipers. Replace it if it’s blown.
2. Listen for the Motor: Turn on the wipers and listen for the motor. If you hear it running but the wipers don’t move, the linkage might be the issue.
3. Inspect the Linkage: If the motor works, inspect the linkage connecting the motor to the wipers. Look for any disconnections or broken parts.
4. Check for Obstructions: Ensure there are no physical obstructions like ice or debris blocking the wiper blades.
5. Test the Switch: If all else seems fine, the problem might be with the wiper switch itself.
