Solution

1. Preparation

Ensure the vehicle is parked with the ignition off.
Gather necessary tools: OBD-II scanner (if applicable), flathead screwdriver, and a multimeter.

2. Inspect Wiper Control Stalk

Remove the steering column cover using a flathead screwdriver.
Visually inspect the wiper control stalk for any signs of damage.
If damage is found, proceed to replace the wiper control stalk.

3. Check Wiper Motor Connections

Locate the wiper motor under the hood by following the wiper arms to the base.
Disconnect the wiper motor electrical connector.
Use a multimeter to test for voltage at the connector; check for any intermittent connections.
If poor connectivity is found, clean the terminals and reconnect. If the motor is faulty, it should be replaced.

4. Update Software

Connect the vehicle to a Wi-Fi network.
Access the software update section through the vehicle’s settings.
Follow the on-screen instructions to ensure the vehicle’s software is up to date.

5. Perform Master Reset

With the vehicle in park, press and hold both scroll wheels on the steering wheel until the touchscreen turns black.
Release the scroll wheels when the Tesla logo appears; this will reset the system.
Test the wipers to see if the issue persists.
