Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, basic socket set, and flathead screwdriver.
Ensure the vehicle is parked on a flat surface and turn off the ignition.
Disconnect the vehicle's 12V battery for safety.

2. Inspect and Replace the Fuse

Locate the fuse box (refer to the owner's manual for the exact location).
Use a fuse puller or pliers to carefully remove the windshield wiper fuse.
Check the fuse for continuity using a multimeter. If blown, replace it with a new fuse of the same amperage.

3. Test the Wiper Motor

Reconnect the battery and access the wiper motor (usually located under the cowl).
Disconnect the electrical connector to the wiper motor.
Using a multimeter, check for voltage at the connector while activating the wiper switch. If no voltage is detected, further electrical diagnostics may be needed.
If voltage is present, apply direct power to the motor to check for operation.

4. Inspect Wiper Linkage

If the wiper motor works but wipers do not move, check the wiper linkage.
Remove the wiper arms using a flathead screwdriver to pry off the caps and a socket to remove the nut.
Inspect the linkage for any disconnections or damage; replace if necessary.

5. Reassemble and Test

Reinstall the wiper motor and linkage if they were removed.
Reattach the wiper arms securely and replace any covers.
Reconnect the battery and test the windshield wipers for proper operation.
