Solution

1. Preparation

Gather tools and parts needed for repair.
Disconnect the battery to ensure safety while working on the electrical system.

2. Inspect Wiper Switch

Remove the steering column cover using a screwdriver.
Disconnect the wiper switch connector.
Test the switch continuity with a multimeter. Replace if faulty.

3. Check and Replace Fuse

Locate the fuse box (typically under the dashboard or hood).
Identify the wiper fuse using the diagram on the fuse box cover.
Remove the fuse and check for continuity. Replace with the same amperage if blown.

4. Test Wiper Motor

Disconnect the wiper motor connector.
Use jumper wires to connect the motor directly to the battery.
If the motor operates, the issue lies elsewhere; if not, replace the motor.

5. Inspect Wiring and Connectors

Visually inspect the wiring harness leading to the wiper motor for fraying or damage.
Clean any corroded connectors with electrical contact cleaner.
Reconnect any loose connectors securely and check the integrity of the wires.

6. Verify Relay Operation

Locate the wiper relay in the fuse box or relay box.
Swap it with a similar relay (if available) to test its functionality.
If the wipers work with the swapped relay, replace the defective relay.
