Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface with the ignition turned off.

2. Check and Replace the Fuse

Tools Required: Fuse puller or needle-nose pliers
Locate the fuse box, typically located under the dashboard near the driver's side or under the hood.
Identify and remove the wiper fuse using the diagram on the fuse box cover.
Inspect the fuse for continuity; replace if blown with a fuse of the same amperage.

3. Inspect the Wiper Motor and Connections

Tools Required: Screwdriver set, multimeter
Remove the plastic cover or panel to access the wiper motor.
Disconnect the electrical connector from the wiper motor.
Use a multimeter to check for voltage at the connector while activating the wiper switch. If there is no voltage, the issue may be with the switch or wiring.
If voltage is present, connect the motor directly to a power source to check for functionality. If the motor does not operate, replace the wiper motor.

4. Inspect Wiper Linkage

Tools Required: Socket set
Remove the wiper arms using a puller if necessary.
Check the wiper linkage for any bending, disconnects, or wear. If damaged, replace the linkage assembly.

5. Test Washer Fluid System

Tools Required: None
Check the washer fluid reservoir for fluid levels and inspect the pump for functionality.
If the pump does not activate, replace the washer pump.
