Solution

1. Preparation

Gather tools and parts required.
Disconnect the vehicle battery to ensure safety.

2. Inspect and Replace the Fuse

Locate the fuse box (usually under the dashboard or in the engine bay).
Remove the wiper fuse and visually inspect it for damage.
If blown, replace it with a fuse of the same amperage.

3. Test and Replace the Wiper Motor

Reconnect the battery and activate the wiper switch.
Use a multimeter to check for voltage at the wiper motor connector.
If no voltage is present, the wiper motor may need to be replaced.
To replace the motor:
- Disconnect the wiper motor harness.
- Remove the mounting bolts securing the motor.
- Install the new motor, securing it with bolts to the specified torque (usually around 8-10 Nm).
- Reconnect the motor harness.

4. Inspect and Replace the Wiper Switch

If the motor tests fine, remove the steering column cover to access the wiper switch.
Disconnect the wiring harness from the switch.
Test the switch with a multimeter to verify its operation; if faulty, replace it.
Reinstall the new wiper switch and steering column cover.
