Solution

1. Preparation

Gather tools: socket set, multimeter, OBD-II scanner, flathead screwdriver, and a new fuse (if needed).
Park the vehicle on a flat surface and ensure the ignition is off.

2. Check and Replace the Fuse

Locate the fuse box, typically found under the dashboard or in the engine compartment.
Use a fuse puller or flathead screwdriver to remove the wiper fuse.
Inspect the fuse visually; if broken, replace it with a fuse of the same amperage.
Reinsert the fuse and check if the wipers function properly.

3. Inspect and Repair Wiring

Visually inspect the wiring harness connected to the wiper motor for any signs of wear or damage.
Use a multimeter to check for continuity in the wires leading to the wiper motor.
Repair any damaged wires with appropriate electrical connectors or tape.

4. Test and Replace the Wiper Motor

If the motor does not operate when direct power is applied, it may need replacement.
Disconnect the battery to ensure safety before working on electrical components.
Remove the wiper arms using a socket set, then unbolt the wiper motor from its mounting.
Disconnect the wiring harness from the motor and remove it from the vehicle.
Install the new wiper motor by reversing the removal steps, ensuring all connections are secure.

5. Reassemble and Test

Reinstall the wiper arms in the correct position (usually in the resting position).
Reconnect the battery and test the wipers to ensure they operate correctly.
