Solution

1. Preparation

Gather tools: socket set, multimeter, wire brush, and wiper motor replacement if necessary.
Ensure the vehicle is parked on a level surface and the ignition is turned off.

2. Inspect and Replace the Fuse

Locate the fuse box, usually found under the dashboard or hood.
Remove the wiper fuse using a fuse puller or pliers.
Inspect the fuse for any signs of being blown (broken filament).
If blown, replace it with a new fuse of the same amperage.

3. Test the Wiper Motor

Disconnect the wiper motor connector.
Use a multimeter to check for voltage at the connector when the wiper switch is activated.
If no voltage is present, further investigate the wiring harness or switch.
If voltage is present, connect the motor directly to a power source to verify if it operates.

4. Inspect the Wiper Linkage

Remove the wiper arms by loosening the retaining nuts with a socket set.
Carefully pull the wiper arms off the splines on the motor shaft.
Inspect the wiper linkage for wear or disconnections and replace any damaged components.

5. Check the Washer System

Inspect the washer fluid reservoir for adequate fluid levels.
Disconnect the washer hose and check for clogs; clear any blockages if present.
Reconnect the hose and test the washer function by activating the washer switch.
