Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to prevent electrical shock.
Ensure the vehicle is on a flat surface and is secure.

2. Inspect and Replace Fuse

Tools Required: Fuse puller or needle-nose pliers.
Locate the fuse box (usually under the dashboard or in the engine compartment).
Identify the wiper fuse (refer to the diagram on the fuse box cover).
Pull the fuse and inspect it for continuity; replace it if blown.

3. Test and Replace Wiper Switch

Tools Required: Multimeter, screwdriver.
Remove the steering column cover by unscrewing the screws.
Disconnect the wiper switch connector.
Set the multimeter to continuity test mode.
Check for continuity across the switch terminals when activated; replace the switch if it fails the test.

4. Inspect Wiper Motor and Wiring

Tools Required: Socket set, multimeter.
Access the wiper motor by removing the cowl panel (unscrew the necessary fasteners).
Inspect the motor for physical damage and ensure all connections are secure.
Test the wiring for continuity; repair or replace any damaged wires.

5. Test and Replace Wiper Motor

Tools Required: Socket set, multimeter.
Connect the wiper motor directly to the battery using jumper wires to confirm operation.
If the motor does not operate, replace it with a new unit.
Reassemble all components and ensure everything is securely fastened.
