Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety while working on electrical components.

2. Check Wiper Fuse

Locate the fuse box (usually under the dashboard or in the engine compartment).
Remove the wiper fuse using a fuse puller.
Inspect the fuse for continuity; replace it if blown.

3. Test Wiper Motor

Disconnect the electrical connector from the wiper motor.
Use a multimeter to check for power at the connector when the wiper switch is activated.
If power is present, connect the motor directly to the battery to confirm it operates.

4. Inspect Wiper Linkage

Remove the wiper arms using a socket set (usually a 10mm socket).
Detach the cowl cover to access the linkage.
Inspect the linkage for any broken or loose parts; tighten or replace as necessary.

5. Replace Wiper Blades

Lift the wiper arms away from the windshield.
Slide the old wiper blades off the arms and replace them with new ones.
Ensure the new blades click securely into place.
