Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the 12V battery to prevent electrical shock.
Ensure the vehicle is in a safe, stable position.

2. Inspect and Replace the Wiper Fuse

Locate the fuse box (typically under the dashboard or in the trunk).
Remove the cover and find the wiper fuse (refer to the owner's manual for the exact location).
Use a fuse puller or pliers to remove the fuse.
Inspect the fuse for any signs of damage or a blown filament.
Replace with a new fuse of the same amperage if necessary.

3. Test and Replace the Wiper Motor

Reconnect the battery temporarily.
Access the wiper motor (usually located under the windshield cowl).
Disconnect the wiper motor connector.
Use a multimeter to check for voltage at the connector when the wiper control is activated.
If voltage is present but the motor does not operate, replace the wiper motor.
If no voltage is detected, further diagnosis of the control circuit is needed.

4. Check and Secure Connections

Inspect all wiring and connectors leading to the wiper motor for damage or corrosion.
Clean any corrosion with electrical contact cleaner.
Secure all connections tightly.

5. Reassembly

Reinstall any covers or panels that were removed.
Reconnect the battery.
Ensure wiper blades are properly attached.
