Solution

1. Preparation

Ensure the vehicle is parked on a flat surface and the engine is off.
Gather necessary tools and parts, and disconnect the battery to ensure safety.

2. Inspect and Replace Wiper Blades

Tools Required: Flathead screwdriver, replacement wiper blades.
Lift the wiper arms away from the windshield.
Use a flathead screwdriver to release the blades from the wiper arms.
Install new wiper blades by aligning them with the arm and clicking them into place.

3. Check and Replace the Wiper Fuse

Tools Required: Fuse puller or needle-nose pliers, replacement fuse.
Locate the fuse box (usually under the dashboard or in the engine compartment).
Identify the wiper fuse using the diagram on the fuse cover.
Remove the fuse and inspect it for continuity; replace with a new fuse of the same amperage if blown.

4. Test and Replace the Wiper Motor

Tools Required: Socket set, multimeter, replacement wiper motor.
Locate the wiper motor, typically found under the cowl panel.
Disconnect the electrical connector and use a multimeter to test for voltage while activating the wiper switch.
If no voltage is detected, check wiring; if voltage is present, replace the wiper motor.
Unbolt the motor from its mount and install the new motor, ensuring to reconnect the electrical connector.

5. Reassemble and Test

Reassemble any components that were removed during the inspection or replacement process.
Reconnect the battery and test the wipers at various settings to ensure proper functionality.
