Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the battery to prevent electrical shock.

2. Check and Replace Wiper Fuse

Locate the fuse box, typically found under the dashboard or in the engine compartment.
Identify the wiper fuse using the diagram on the fuse box cover.
Use a fuse puller to remove the fuse and check for any visible damage.
Replace with an identical fuse (typically a 15A or 20A, check owner's manual for specifics).

3. Inspect Wiper Motor and Switch

Reconnect the battery.
Turn the ignition on and activate the wipers while checking the wiper motor.
If the motor does not engage, remove it by unscrewing the mounting bolts and disconnecting the wiring harness.
Test the wiper motor by connecting it directly to the battery; if it does not work, replace the motor.

4. Examine Wiper Linkage

If the motor works, reattach it and check the wiper linkage.
Remove the plastic covers at the base of the windshield.
Inspect the linkage for loose connections or damage. If damaged, replace the linkage assembly.

5. Reassemble and Test

Reattach any components removed during the repair.
Ensure all connections are secure and the wiper arms are properly positioned.
Perform a final test of the wipers to ensure they operate correctly.
