Solution

1. Preparation

Gather necessary tools: socket set, multimeter, flat-head screwdriver, and a replacement wiper motor if needed.
Ensure the vehicle is parked on a flat surface and turned off.
Disconnect the vehicle's 12V battery to prevent any electrical shock.

2. Inspect and Replace Fuse

Locate the fuse box; refer to the owner's manual for the specific location of the wiper fuse.
Use the socket set to remove the fuse cover.
Inspect the wiper fuse; if it appears blown (broken filament), replace it with a new fuse of the same amperage.
Reinstall the fuse cover and reconnect the battery.

3. Test Wiper Motor

Reconnect the vehicle's battery.
Activate the wipers to see if they respond. If not, proceed to check the motor.
Remove the wiper arms by loosening the retaining nut with a socket.
Disconnect the wiper motor wiring harness.
Use a multimeter to check for voltage at the motor connector when wipers are activated. If voltage is present, the motor is likely faulty.

4. Replace Wiper Motor (if necessary)

If the motor is defective, remove the wiper motor assembly by unscrewing the mounting bolts.
Install the new wiper motor by reversing the removal steps, ensuring all connections are secure.
Reattach the wiper arms in their original position and secure them with the retaining nuts.

5. Final Check

Reconnect the vehicle's battery if it was disconnected.
Test the wipers and washer fluid system to ensure full functionality.
