Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, and screwdriver.
Ensure the vehicle is parked on a flat surface and the ignition is off.
Disconnect the battery to prevent electrical shock.

2. Inspect and Replace the Fuse

Locate the fuse box, generally found under the dashboard or in the trunk.
Remove the cover and locate the wiper fuse (refer to the owner's manual for the specific location).
Check the fuse for continuity; if blown, replace it with an identical fuse (typically, a 10A or 15A fuse).
Reinstall the fuse cover and reconnect the battery.

3. Test and Replace the Wiper Motor

If the fuse is intact, locate the wiper motor (usually found at the base of the windshield).
Disconnect the wiring harness from the motor.
Use a multimeter to check for voltage at the connector while activating the wipers.
If no voltage is detected, trace back to the relay and control stalk.
If voltage is present but the motor does not operate, replace the wiper motor.
To replace, unbolt the motor from its mount, remove the wiper linkage if necessary, and install the new motor in reverse order.

4. Reassemble and Test

Reconnect all wiring and ensure all connectors are secure.
Reinstall any components or covers that were removed during the process.
Reconnect the battery and perform a test of the windshield wipers.
