Solution

1. Preparation

Gather tools including a multimeter, socket set, and flathead screwdriver.
Ensure the vehicle is parked on a flat surface and the ignition is off.

2. Inspect and Replace Fuse

Locate the fuse box, typically found under the dashboard or in the engine compartment.
Use the fuse puller tool to remove the wiper motor fuse (consult the owner's manual for the correct fuse position).
Inspect the fuse for continuity using a multimeter; replace it with a new fuse of the same amperage if blown.

3. Test the Wiper Motor

Disconnect the wiper motor's electrical connector.
Use a multimeter to check for power at the connector with the wiper switch in the 'on' position.
If power is present, connect the motor directly to a 12V power source to test functionality. If it does not work, replace the motor.

4. Inspect Wiper Linkage

Remove the wiper arms by loosening the nuts with a socket set.
Detach the wiper motor from its mounting points to access the linkage.
Inspect the linkage for any signs of wear, damage, or disconnection. Reconnect or replace as necessary.

5. Reassemble Components

Reattach the wiper motor and linkage securely.
Reinstall the wiper arms, ensuring they are positioned correctly.
Test the wipers to confirm functionality.
