Solution

1. Preparation

Gather necessary tools: OBD-II scanner, multimeter, socket set, and a flathead screwdriver.
Ensure the vehicle is in park and the ignition is off before starting any work.

2. Inspect and Replace Fuse

Locate Fuse Box:
- Open the driver’s side door and remove the cover for the fuse box located under the dashboard.
Check Wiper Fuse:
- Identify the fuse for the windshield wipers (refer to the fuse box diagram).
- Remove the fuse using a fuse puller or pliers and check if it is blown.
Replace Fuse:
- If blown, replace it with a new fuse of the same amperage rating (usually marked on the fuse itself).

3. Inspect Wiper Motor

Access Motor:
- Remove the wiper arms using a socket set (typically a 13mm socket).
- Remove any covers or panels to access the wiper motor.
Check Connections:
- Inspect electrical connectors for corrosion or loose connections.
Test Motor:
- Apply direct battery voltage to the wiper motor to test its operation. If it runs, the motor is functional; if not, it may need replacement.

4. Replace Wiper Motor (if necessary)

Remove Old Motor:
- Unscrew the mounting bolts securing the wiper motor and remove it from its bracket.
Install New Motor:
- Position the new motor and secure it with bolts to the bracket.
Reconnect Wiring:
- Reconnect the electrical connectors ensuring a tight fit.

5. Reassemble Wiper Arms and Covers

Reconnect Wiper Arms:
- Position the wiper arms back onto the motor shafts, ensuring they are aligned properly.
Secure Covers:
- Replace any covers or panels removed during the process.
