Solution

1. Preparation

Gather tools: multimeter, fuse puller, screwdrivers, and a replacement wiper motor (if needed).
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the vehicle's battery to ensure safety while working on electrical components.

2. Inspect and Replace the Fuse

Locate the fuse box, typically found under the dashboard or in the engine compartment.
Use a fuse puller to remove the wiper fuse.
Inspect the fuse for any signs of damage or breakage; replace it with a new fuse of the same amperage if necessary.

3. Test and Replace the Wiper Motor

Locate the wiper motor, often positioned at the base of the windshield.
Disconnect the motor's wiring harness.
Use a multimeter to check for power at the motor connector while engaging the wiper switch.
If no power is detected, further investigate the wiring or switch.
If power is present but the motor does not operate, remove the motor by unscrewing the mounting bolts and replacing it with a new motor.
Reconnect the wiring harness and secure the motor in place.

4. Reassemble and Test

Reinstall any components removed during the process, ensuring all screws and bolts are tightened to prevent rattling.
Reconnect the vehicle's battery.
Test the windshield wipers and washer system to confirm they are functioning correctly.
