Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the ignition is off.
Disconnect the battery to avoid electrical shock.

2. Inspect and Replace Wiper Blade Fuse

Locate the fuse box, usually found under the dashboard or near the engine compartment.
Remove the wiper fuse using a fuse puller.
Check the fuse for continuity. If it is blown, replace it with a new fuse of the same amperage.

3. Test and Replace Wiper Motor

Reconnect the battery and activate the wiper switch to check if the motor operates.
If the motor does not work, disconnect it from the wiring harness.
Use jumper wires to connect the wiper motor directly to the battery. If it does not run, replace the motor.
If functional, proceed to inspect the mounting and ensure it is securely fastened.

4. Inspect and Repair Wiring

Check the wiring harness leading to the wiper motor for any visible damage.
Repair or replace any damaged wires and ensure all connectors are secure.

5. Reassemble and Test

Reinstall any components you removed during the inspection.
Ensure everything is properly secured and reconnect the battery.
Test the wipers to ensure they are functioning correctly.
