Solution

1. Preparation

Tools Required: Multimeter, basic socket set, torque wrench, OBD-II scanner, safety glasses.
Ensure the vehicle is turned off and parked on a level surface.
Disconnect the negative terminal of the battery to prevent electrical shock.

2. Inspect and Replace the Wiper Fuse

Locate the fuse box (typically under the dashboard or in the trunk).
Refer to the owner's manual to find the specific fuse related to the wipers.
Remove the fuse using a fuse puller or pliers.
Inspect the fuse for continuity; replace if blown with a fuse of the same amperage.

3. Check the Wiper Motor

Reconnect the battery terminal temporarily.
Test the wiper motor by engaging the wiper switch to see if it activates.
If it does not, proceed to remove the wiper motor:
- Access the wiper motor by removing the wiper arms (using a puller if necessary).
- Unscrew the wiper motor from its mount and disconnect the wiring harness.
Test the motor with a multimeter to ensure it receives power when the switch is activated.

4. Replace the Wiper Motor (if necessary)

If the wiper motor is faulty, install the new motor:
- Connect the wiring harness to the new motor.
- Secure the motor to its mount with the screws.
- Reinstall the wiper arms and ensure they are positioned correctly.

5. Final Assembly and Testing

Reconnect the negative battery terminal.
Check the operation of the wipers by activating them in all modes (low, high, and intermittent).
Ensure wiper fluid sprays correctly.
