Solution

1. Preparation

Gather tools: multimeter, socket set, screwdrivers, and a new wiper motor (if necessary).
Disconnect the vehicle battery to ensure safety during repairs.

2. Inspect and Replace Fuses

Locate the fuse box, typically found under the dashboard or in the engine compartment.
Identify the wiper motor fuse using the diagram on the fuse box cover.
Remove the fuse and inspect it for damage; replace it if blown with a fuse of the same amperage.

3. Access and Test the Wiper Motor

Remove the wiper arms by loosening the nuts holding them in place; use a puller if necessary.
Detach the cowl cover to access the wiper motor.
Disconnect the electrical connector from the wiper motor.
Use a multimeter to check for power at the motor connector when the wiper switch is activated.
If no power is present, trace back to the switch and wiring for faults.
If power is present, proceed to replace the wiper motor.

4. Replace the Wiper Motor

Unscrew the mounting bolts securing the wiper motor and remove it from its bracket.
Install the new wiper motor in the reverse order of removal, ensuring it is aligned properly.
Reconnect the electrical connector securely.

5. Reassemble Components

Reinstall the cowl cover and ensure all clips and screws are properly secured.
Reattach the wiper arms to their original positions, ensuring they are aligned correctly.
Reconnect the vehicle battery.
