Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is parked on a flat surface and the ignition is off.
Disconnect the battery to prevent electrical shock.

2. Check and Replace Fuse

Locate the fuse box (usually found under the dashboard or in the engine compartment).
Identify the wiper fuse (refer to the fuse box diagram).
Remove the fuse using a fuse puller and inspect it.
- If blown, replace with a fuse of the same amperage (typically 20A for wipers).

3. Test and Replace Wiper Motor

Reconnect the battery and turn on the ignition.
Check for power at the wiper motor connector while activating the wiper switch.
- If no power: The issue may lie within the control switch or wiring.
- If power is present:
  - Remove the wiper arms by unscrewing the retaining nuts.
  - Unbolt the wiper motor from its mounting location.
  - Disconnect the electrical connector.
  - Replace with a new wiper motor, reversing the removal steps.
  - Torque specifications: Secure the wiper motor bolts to 10 Nm.

4. Inspect and Replace Wiper Control Switch

If the wiper motor replacement did not resolve the issue, remove the steering column cover.
Disconnect the wiper control switch from the wiring harness.
Test the switch for continuity using a multimeter.
- If defective, replace with a new wiper control switch.
Reassemble all components securely.
