Solution

1. Preparation

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

2. Inspect and Replace the Wiper Fuse

Locate the fuse panel (usually found under the dashboard or in the engine compartment).
Remove the wiper fuse using a fuse puller or pliers.
Check the fuse visually and with a multimeter for continuity. If blown, replace with a fuse of the same amperage.

3. Test the Wiper Relay

Identify the wiper relay location in the fuse box.
Remove the relay and check it for continuity using a multimeter.
If the relay is faulty, replace it with a new one.

4. Check Power to the Wiper Motor

Reconnect the battery.
With the wiper switch in the "on" position, use a multimeter to check for voltage at the wiper motor connector.
If there is no voltage, trace back to the switch or wiring for faults.

5. Inspect the Wiper Motor and Linkage

If power is present at the motor, remove it from its mounting.
Check the wiper linkage for any signs of wear or obstruction.
If the motor is defective, replace it with a new unit, ensuring to torque bolts to manufacturer specifications (typically around 8-10 Nm).
