Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, screwdrivers, and safety gloves.
Disconnect the negative battery terminal to prevent electrical shock.

2. Inspect and Replace the Fuse

Locate the fuse box (usually under the dashboard or in the engine compartment).
Remove the windshield wiper fuse and inspect it for continuity.
If blown, replace it with a fuse of the same amperage (typically 20A).

3. Replace the Wiper Motor (if necessary)

Remove Wiper Arms:
- Use a socket set to remove the nuts securing the wiper arms to the motor shaft.
- Gently pull the wiper arms off the shafts.
Access the Wiper Motor:
- Remove any covers or panels blocking access to the wiper motor.
- Unscrew and remove the motor mounting bolts using a socket set.
Disconnect the Wiper Motor:
- Unplug the electrical connector from the wiper motor.
Install New Wiper Motor:
- Position the new wiper motor in place and secure it with mounting bolts.
- Reconnect the electrical connector to the new motor.

4. Reassemble Components

Reinstall the wiper arms by aligning them properly on their shafts and securing them with nuts.
Replace any covers or panels that were removed during access.

5. Final Checks

Reconnect the negative battery terminal.
Test the wiper functionality at all speeds and modes (intermittent, low, high).
