Solution

1. Preparation

Ensure the vehicle is parked safely and on a level surface.
Disconnect the vehicle's 12V battery to prevent electrical shock.
Gather necessary tools and parts.

2. Inspect and Replace Fuse

Locate the fuse box, typically found under the dashboard or in the trunk.
Identify and remove the fuse designated for the windshield wipers (consult the owner’s manual for the correct fuse location).
Inspect the fuse for continuity using a multimeter; replace it if blown with a new fuse of the same amperage.

3. Test and Replace Wiper Motor

Reconnect the battery and test the wiper motor by activating the wipers from the control stalk.
If the motor remains non-functional, disconnect the battery again.
Remove the wiper arm covers and the arms themselves (typically requires a puller tool).
Unscrew and detach the wiper motor from its mount.
Install the new wiper motor by reversing the removal steps, ensuring all connectors are securely attached.
Torque the mounting bolts to the manufacturer's specifications.

4. Final Assembly

Reinstall the wiper arms onto the motor's splines, ensuring they are correctly aligned.
Replace any covers and secure them properly.
Reconnect the vehicle's battery.
