Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, and screwdriver.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to avoid any electrical shorts.

2. Replace the Wiper Fuse

Locate the fuse box, typically found under the dashboard or in the engine compartment.
Identify the wiper fuse using the fuse diagram.
Remove the fuse using a fuse puller or pliers.
Inspect the fuse for continuity. If blown, replace it with a fuse of the same amperage.

3. Inspect and Replace the Wiper Motor

Remove the plastic cover from the wiper assembly to access the motor.
Disconnect the electrical connector from the wiper motor.
Unbolt the wiper motor from its mounting points using the socket set.
Install the new wiper motor by reversing the removal steps, ensuring all connections are secure.
Torque the mounting bolts to the manufacturer specifications (typically around 8-10 Nm).

4. Reconnect the Battery

Reconnect the negative terminal of the battery.
Ensure all tools are removed from the engine bay.
