Solution

1. Preparation

Tools Required: Multimeter, OBD-II scanner, basic hand tools (screwdrivers, socket set).
Disconnect the negative terminal of the battery to prevent electrical shock.

2. Check the Wiper Fuse

Locate the fuse box (typically under the dashboard or in the front trunk).
Identify the wiper fuse using the fuse diagram.
Remove the fuse and check for continuity using a multimeter; replace if blown.

3. Inspect Wiper Motor Connections

Remove any panels obstructing access to the wiper motor.
Carefully disconnect the wiring harness from the wiper motor.
Inspect for corrosion or damage; clean or repair as necessary.
Reconnect the wiring harness securely.

4. Test the Wiper Motor

With the battery still disconnected, apply 12V power directly to the wiper motor terminals using jumper wires.
Observe if the motor activates; if it does not work, it may require replacement.

5. Replace Wiper Motor (if necessary)

Remove the wiper arm by loosening the nut with a socket set.
Unbolt the wiper motor from its mount.
Install the new wiper motor in reverse order of removal.
Reattach the wiper arm and torque the nut to manufacturer specifications.
