Solution

1. Preparation

Tools Required: Socket set, multimeter, flathead screwdriver, replacement fuse (if necessary).
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the battery to avoid electrical shock.

2. Inspect and Replace Fuse

Locate the fuse box (typically found under the dashboard or in the engine compartment).
Remove the fuse related to the windshield wipers using a fuse puller or flathead screwdriver.
Inspect the fuse for continuity; if blown, replace it with a new fuse of the same amperage.

3. Test Wiper Motor

Reconnect the battery.
Use a multimeter to check for voltage at the wiper motor connector when the wiper switch is activated.
If voltage is present but the motor does not operate, replace the wiper motor.

4. Check Wiper Linkage

Remove the wiper arms using a puller if necessary.
Inspect the linkage assembly for any signs of wear or damage.
If the linkage is damaged, replace it with a new assembly.

5. Install New Wiper Blades

Remove old wiper blades from the arms.
Attach new wiper blades, ensuring they are securely locked into place.
