Solution

1. Preparation

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

2. Inspect and Replace Fuse

Locate the fuse box (usually under the dashboard or in the engine compartment).
Remove the wiper fuse using a fuse puller or pliers.
Check the fuse for continuity—replace it with a new fuse of the same amperage if blown.

3. Replace Wiper Motor (if faulty)

Remove the wiper arms by unscrewing the retaining nuts using a socket wrench.
Carefully pull the wiper arms off the splines; use a puller if necessary.
Disconnect the electrical connector from the wiper motor.
Remove the mounting bolts securing the wiper motor using a socket wrench and lift the motor out.
Install the new wiper motor, securing it with the mounting bolts and reconnecting the electrical connector.

4. Reinstall Wiper Arms

Align the wiper arms to their original positions on the splines.
Tighten the retaining nuts securely to ensure the arms do not become loose.
Check the position of the wiper arms when at rest.

5. Final Checks

Reconnect the vehicle’s battery.
Test the wiper operation through all settings (low, high, and wash).
