Solution

1. Preparation

Gather tools: A flathead screwdriver, a multimeter, and a replacement fuse if necessary.
Ensure the vehicle is in "Park" mode and the ignition is off before starting any work.

2. Check Wiper Control Settings

Access the touchscreen interface.
Navigate to the "Controls" menu and select "Wipers."
Ensure the wiper settings are set to the desired mode (e.g., Auto, Intermittent).

3. Inspect and Replace Fuses

Locate the fuse box, which is usually found under the dashboard or in the front trunk area.
Use the flathead screwdriver to gently pry open the fuse box cover.
Refer to the fuse diagram to identify the windshield wiper fuse.
Use the multimeter to check the fuse for continuity. Replace it if it's blown (typically a 15A fuse).

4. Test the Wiper Motor

Disconnect the wiper motor’s electrical connector.
Use the multimeter to check for voltage at the connector while activating the wiper control.
If voltage is present but the motor does not operate, replace the wiper motor.
If no voltage is present, trace the wiring back to the control unit for faults.

5. Inspect and Repair the Wiper Linkage

Remove the wiper arms using a puller tool if necessary.
Inspect the wiper linkage for any damage or disconnections.
Reconnect or replace any damaged components as needed.
