Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the vehicle battery to ensure safety.
Position the wipers in the "off" position to facilitate access.

2. Inspect and Replace Fuse

Locate the fuse box (usually under the dashboard or in the engine compartment).
Remove the wiper fuse and test it with a multimeter for continuity.
If blown, replace it with a new fuse of the same amperage.

3. Test and Replace Wiper Motor (if necessary)

Using a multimeter, check for voltage at the wiper motor connector while the switch is activated.
If voltage is present but the motor does not operate, remove the motor:
1. Disconnect the electrical connector.
2. Unscrew the mounting bolts securing the motor.
3. Remove the motor from the wiper assembly.
Install a new wiper motor by reversing the removal steps.

4. Inspect and Repair Wiper Linkage

Remove the wiper arms by loosening the nut at the base of each arm.
Remove the cowl panel to access the wiper linkage.
Inspect the linkage for any signs of wear or disconnection.
If damaged, replace the linkage assembly.

5. Reinstall Components

Reattach the wiper arms, ensuring they are in the correct position.
Reconnect the battery and ensure all electrical connections are secure.
Test the wipers for proper operation.
