Solution

1. Preparation

Gather necessary tools and parts for repair.
Disconnect the negative terminal of the battery to ensure safety during repairs.

2. Check and Replace Fuse

Locate the fuse box as per the Tesla Model S manual.
Remove the wiper fuse and inspect it visually for continuity.
Replace the fuse if it is blown with a new fuse of the same amperage.

3. Inspect and Replace Wiper Motor

If the fuse is intact, locate the wiper motor, which is typically found under the cowl panel.
Remove the cowl panel by unscrewing the necessary fasteners with a socket set.
Disconnect the electrical connector from the wiper motor.
Test the motor by applying 12V directly from a power source.
If the motor does not operate, replace it with a new wiper motor.

4. Reassemble Components

Reconnect the electrical connector to the new wiper motor.
Reattach the cowl panel and secure it with the fasteners previously removed.
Reconnect the battery terminal.

5. Final Checks

Ensure that the wiper blades are securely attached to the arms.
Test the wipers to confirm proper functionality.
