Solution

1. Preparation

Ensure the vehicle is parked on a flat surface and powered off.
Gather tools: OBD-II scanner, multimeter, and any necessary replacement parts.

2. Soft Reset

With the vehicle in park, hold down the scroll wheels on the steering wheel.
Wait for the central display to reboot (approximately 10-15 seconds).
Check if the wipers turn off after the reset.

3. Update Software

Navigate to the "Software" section in the touchscreen.
Connect to Wi-Fi if updates are available.
Follow prompts to install any available updates.
Restart the vehicle after updates are complete.

4. Inspect the Wiper Motor

Open the front trunk (frunk) and locate the wiper motor.
Disconnect the wiper motor's electrical connector.
Use a multimeter to check for proper voltage at the connector while activating the wipers.
If voltage is present but wipers still do not respond, replace the wiper motor.

5. Repair or Replace Components

If the wiper motor tests faulty, remove it by unscrewing the mounting bolts.
Install the new wiper motor by reversing the removal steps.
Reconnect the electrical connector and test the wipers again.
