Solution

1. Preparation

Gather tools: socket set, multimeter, flat-head screwdriver, and replacement parts as needed.
Disconnect the negative battery terminal to prevent electrical shock.
Allow the vehicle to cool down if it has been recently used.

2. Inspect and Replace the Wiper Fuse

Locate the fuse box. It is usually found under the dashboard or in the engine compartment.
Using the fuse puller or pliers, remove the wiper fuse and visually inspect it for a broken filament.
If the fuse is blown, replace it with a new fuse of the same amperage (refer to the owner's manual for specifications).

3. Check the Wiper Switch

Remove the steering column cover using a flat-head screwdriver.
Disconnect the wiper switch connector and use a multimeter to check for continuity.
If the switch is faulty, replace it with a new one.

4. Inspect and Test the Wiper Motor

Locate the wiper motor, usually found under the cowl panel near the base of the windshield.
Disconnect the electrical connector from the wiper motor.
Use a multimeter to check for voltage at the motor connector while activating the wiper switch.
If there is no voltage, trace the wiring for damage or corrosion. Repair as necessary.
If there is voltage and the motor does not operate, replace the wiper motor.

5. Check Wiper Linkage

Remove the wiper arms using a socket wrench and pull them off the motor spline.
Inspect the wiper linkage for any binding, wear, or disconnection. If damaged, replace the linkage assembly.
Reinstall the wiper arms and ensure they are properly aligned.
