Solution

1. Preparation

Gather all necessary tools and parts.
Tools Required:
- Socket set
- Screwdriver set
- Multimeter
- Torque wrench
Ensure the vehicle is parked on a flat surface and the ignition is turned off.

2. Inspect and Replace Wiper Motor

Access the Wiper Motor:
- Remove the plastic cover beneath the windshield (if applicable) using appropriate screwdrivers or a trim removal tool.
- Unclip any retaining clips that secure the motor assembly.
Disconnect the Wiper Motor:
- Locate the wiper motor connector and carefully disconnect it. Make sure to avoid damaging the wiring harness.
Test the Wiper Motor:
- Use a multimeter to check for continuity in the motor. If there is no continuity, the motor likely requires replacement.
Replace the Wiper Motor (if necessary):
- Remove the mounting bolts securing the wiper motor using a socket set.
- Install the new wiper motor by reversing the removal process. Torque the bolts to the manufacturer's specifications (check service manual for specific torque values).

3. Reassemble Components

Reconnect the wiper motor electrical connector.
Replace the plastic cover and secure it with clips or screws.
Ensure all tools are removed from the engine bay.

4. Test the Wipers

Turn on the vehicle and test the wiper functionality in all modes to ensure they operate correctly.
