Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, and screwdriver.
Disconnect the vehicle battery to ensure safety while working on electrical components.

2. Inspect the Wiper Switch

Remove the steering column cover using a screwdriver.
Locate the wiper switch connector.
Use a multimeter to test for continuity when the switch is activated.
- If there is no continuity, replace the wiper switch.

3. Check and Replace the Wiper Fuse

Locate the fuse box under the dashboard or in the engine compartment.
Identify the wiper fuse using the diagram on the fuse box cover.
Remove the fuse and inspect it; replace with a fuse of the same amperage if blown.

4. Test and Replace the Wiper Motor

Locate the wiper motor at the base of the windshield.
Disconnect the motor's electrical connector.
Use a multimeter to test the motor for voltage when the wiper switch is activated.
- If there is no voltage, trace back to the relay or wiring.
- If there is voltage and the motor does not function, replace the wiper motor.

5. Inspect and Replace the Wiper Relay

Access the relay box, typically located near the fuse box or under the dashboard.
Identify the wiper relay using the diagram.
Remove the relay and test it for continuity with a multimeter.
- If defective, replace the relay with a new one.
