Solution

1. Preparation

Gather tools: socket set, multimeter, OBD-II scanner, and safety glasses.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the battery to prevent electrical shock.

2. Inspect and Test the Wiper Motor

Sub-steps:
- Locate the wiper motor under the hood, typically near the base of the windshield.
- Use the multimeter to check the voltage at the wiper motor connector when the wiper is activated.
- If no voltage is present, trace back the wiring to find any broken connections or shorts.
- If voltage is present but the motor does not operate, it may need replacement.

3. Replace the Wiper Motor (if necessary)

Sub-steps:
- Remove the wiper arms by unscrewing the nuts holding them in place (use a socket wrench).
- Disconnect the electrical connector from the wiper motor.
- Unbolt the wiper motor from its mount (note any torque specifications).
- Install the new wiper motor in reverse order, ensuring all connections are secure.
- Reattach the wiper arms and ensure they are in the correct position.

4. Replace Wiper Blades (if necessary)

Sub-steps:
- Lift the wiper arms away from the windshield.
- Press the release tab on the wiper blade and slide the old blades off the arm.
- Align the new wiper blades with the arm and slide them into place until they click.
- Lower the wiper arms back onto the windshield.
