2. Replace the Wiper Fuse (if blown)

Locate the fuse box (usually under the dashboard or in the engine compartment).
Remove the fuse panel cover and identify the wiper fuse using the diagram.
Use a fuse puller or pliers to remove the fuse and inspect it.
- If the fuse is blown (the wire inside is broken), replace it with a new fuse of the same amperage.
- Reinstall the fuse panel cover.

3. Inspect and Replace Wiper Motor (if necessary)

Disconnect the negative battery terminal to ensure safety.
Remove the plastic cover or cowl panel where the wiper motor is located (typically requires a screwdriver).
Disconnect the wiring harness from the wiper motor.
Remove the mounting bolts securing the wiper motor and carefully take out the motor.
Install the new wiper motor by reversing the removal steps.
- Torque the mounting bolts to the manufacturer’s specifications.
Reconnect the wiring harness and reinstall the plastic cover.

4. Test Wiper Operation

Reconnect the negative battery terminal.
Turn on the ignition and activate the wipers to confirm they operate properly.
