Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle battery to ensure safety while working on electrical components.

2. Inspect and Replace the Wiper Fuse

Locate the fuse box (usually under the dashboard or in the engine compartment).
Remove the fuse labeled for the windshield wipers (refer to the owner’s manual for the exact location).
Inspect the fuse for continuity; replace it if blown (use a fuse of the same amperage).

3. Test the Wiper Motor

Locate the wiper motor, typically found under the engine cover.
Disconnect the electrical connector from the wiper motor.
Using a multimeter, check for voltage at the connector while the wiper switch is activated.
If voltage is present but the motor does not operate, replace the wiper motor.

4. Inspect Wiring and Connections

Visually inspect the wiring harness for any signs of wear, fraying, or corrosion.
Clean any corroded connections with electrical contact cleaner.
Repair or replace any damaged wiring as necessary.

5. Reassemble and Test

Reconnect the battery and all connectors.
Test the wipers to ensure they are functioning correctly.
