Disconnect the negative battery terminal to ensure safety.

2. Inspect and Replace Fuse

Locate the fuse box, typically found under the dashboard or in the engine compartment.
Identify the wiper fuse using the fuse diagram.
Remove the fuse using a fuse puller or pliers.
Check the fuse for continuity using a multimeter. If blown, replace it with a fuse of the same amperage rating.

3. Test and Replace Wiper Motor

Locate the wiper motor, usually found at the base of the windshield.
Disconnect the electrical connector from the wiper motor.
Using a multimeter, check for voltage at the connector while activating the wipers.
If there is voltage but the motor does not operate, remove the motor by unscrewing it from its mount.
Install the new wiper motor by reversing the removal process, ensuring all connections are secure.

4. Inspect Wiper Linkage

Remove the wiper arms by unscrewing the retaining nuts and lifting them off the motor shaft.
Inspect the wiper linkage assembly for any signs of wear, damage, or disconnection.
Replace any damaged parts of the linkage with new components.

5. Reassemble and Test

Reattach the wiper arms and secure them with the retaining nuts.
Reconnect the negative battery terminal.
Test the wipers to ensure proper operation.
