If your windshield wipers are not working after installation, start by checking the wiper blades and motor connections. Ensure everything is securely attached and free from obstructions. This guide will walk you through troubleshooting steps to get your wipers back in working order.

Why Aren’t My Windshield Wipers Working After Installation?

Check the Wiper Blades and Arms

• Inspect the wiper blades: Ensure they are the correct size and properly attached to the wiper arms. Incorrectly sized blades can cause malfunction.
• Examine the wiper arms: Make sure they are securely fastened to the wiper motor. Loose connections can prevent the wipers from moving effectively.

Verify Electrical Connections

• Check the fuse: A blown fuse is a common cause of wiper failure. Locate the fuse box in your vehicle and inspect the wiper fuse. Replace it if necessary.
• Inspect the wiring: Look for any loose or damaged wires connected to the wiper motor. Poor connections can disrupt the electrical flow needed for operation.

Test the Wiper Motor

• Listen for motor sounds: Turn on the wipers and listen for any humming or movement from the motor. If the motor is silent, it may be faulty.
• Use a multimeter: Test the motor’s electrical connections with a multimeter to ensure it’s receiving power. If not, the issue may be with the vehicle’s electrical system.

Examine the Wiper Linkage

• Check for obstructions: Debris or ice can block the wiper linkage, preventing movement. Clear any obstructions and test the wipers again.
• Inspect the linkage assembly: Ensure that all parts of the linkage are intact and moving freely. Broken or jammed components can hinder wiper function.

How to Fix Windshield Wipers Not Working After Installation

Replace the Fuse

1. Locate the fuse box using your vehicle’s manual.
2. Identify the wiper fuse and remove it.
3. Replace it with a new fuse of the same amperage.

Secure Electrical Connections

• Tighten loose wires: Use a screwdriver or pliers to secure any loose connections.
• Repair damaged wires: Use electrical tape or replace the wiring if necessary to ensure a stable connection.

Adjust or Replace the Wiper Motor

• Realign the motor: If the motor is misaligned, adjust its position for better contact with the linkage.
• Replace the motor: If testing reveals a faulty motor, consider replacing it to restore wiper functionality.

Lubricate the Linkage

• Apply lubricant: Use a silicone-based lubricant on the wiper linkage to reduce friction and improve movement.
• Test the movement: Operate the wipers to ensure smooth and consistent action.
