Solution

1. Preparation

Gather tools: socket set, multimeter, OBD-II scanner, and a replacement fuse if needed.
Ensure the vehicle is parked on a level surface and the engine is off.

2. Inspect and Replace the Fuse

Locate the fuse box: Refer to the owner's manual for the exact location.
Remove the fuse: Use a fuse puller or pliers to carefully extract the wiper fuse.
Check the condition: Inspect the fuse for any signs of being blown (burnt filament).
Replace the fuse: If blown, install a new fuse with the same amperage rating (typically 20A for wipers).
Reassemble the fuse box cover.

3. Test the Wiper Motor

Access the wiper motor: Remove the plastic cover or cowl panel to gain access to the wiper motor.
Disconnect the wiring harness: Carefully unplug the motor connector.
Apply power: Using a multimeter, connect the motor directly to the battery (positive to positive, negative to ground) to see if it operates.
If functioning: Reconnect the motor. If not, replace the wiper motor.

4. Check and Repair the Wiper Linkage

Inspect linkage: Manually check the wiper linkage for any disconnections or broken components.
Reattach or replace components: If any parts are broken, replace them according to manufacturer specifications.
Lubricate: Apply a small amount of grease to the moving parts of the linkage.

5. Reassemble and Test

Reattach any covers: Ensure all components are secured and covers are reinstalled.
Test the wipers: Turn on the wipers to check if they operate correctly.
