Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle's battery to prevent any electrical shorts.
Ensure the area is clear and safe to work on the vehicle.

2. Inspect and Replace Wiper Blades

Tools Required: Flathead screwdriver, replacement wiper blades.
Remove the wiper arm covers (if applicable) using a flathead screwdriver to expose the mounting bolts.
Loosen the bolt securing the wiper arm to the wiper motor shaft and remove the wiper arm.
Replace with new wiper blades by following the manufacturer's instructions for attachment.

3. Check and Replace Wiper Motor

Tools Required: Socket set, multimeter, replacement wiper motor.
Locate the wiper motor, typically found under the hood or beneath the cowl panel.
Disconnect the electrical connector from the motor.
Using a multimeter, test for voltage at the connector when the wiper switch is activated.
If no voltage is present, trace the wiring for damage or shorts.
If voltage is present and the motor does not function, remove the motor by unbolting it from its mount.
Install the new wiper motor, ensuring to torque the mounting bolts to specifications.

4. Check and Replace Fuses

Tools Required: Fuse puller or needle-nose pliers.
Locate the fuse box, typically under the dashboard or in the front compartment.
Identify the wiper fuse using the diagram on the fuse box cover.
Remove the fuse and inspect it for continuity. Replace with a fuse of the same amperage if blown.
