Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the vehicle's 12V battery to ensure safety while working on electrical components.

2. Check and Replace Fuse

Locate the fuse box, typically under the dashboard or in the trunk.
Remove the cover and find the windshield wiper fuse (refer to the owner's manual for exact location).
Use a multimeter to check for continuity. If blown, replace with the same amperage fuse.
Reinstall the fuse cover and reconnect the battery.

3. Inspect and Repair Wiring

Inspect the wiring harness connected to the wiper motor for any visible signs of damage or corrosion.
If damaged, repair the wiring using solder and heat shrink tubing or replace the harness as necessary.
Ensure all connectors are secure and free from corrosion.

4. Test Wiper Motor

Disconnect the wiper motor from its connector.
Use jumper wires to apply power directly to the motor (positive to positive, negative to negative).
If the motor operates, reconnect it properly; if not, replace the wiper motor.

5. Reassemble and Test

Reassemble any components that were removed during the inspection.
Reconnect the vehicle's battery.
Test the windshield wipers to confirm proper operation.
