Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect and Replace Wiper Blades

Remove the wiper arms by lifting the arms away from the windshield.
Unclip the old wiper blades from the arms and replace them with new ones.
Ensure the new blades are securely attached.
Reposition the wiper arms back to their original position.

3. Test the Wiper Motor

Locate the wiper motor, typically found under the cowl area at the base of the windshield.
Disconnect the motor's electrical connector.
Use a multimeter to check for voltage at the connector when the wiper switch is activated.
If voltage is present, replace the wiper motor. If not, further investigate the switch or wiring.

4. Replace the Wiper Fuse

Locate the fuse box (usually under the dashboard or in the engine compartment).
Identify the wiper fuse using the diagram on the fuse box cover.
Remove the fuse using a fuse puller or pliers.
Inspect the fuse for continuity; replace if blown with a fuse of the same amperage.

5. Reassemble and Test

Reconnect the wiper motor and any disconnected components.
Reconnect the negative battery terminal.
Test the wipers in various settings to ensure proper operation.
