Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle's 12V battery to ensure safety during repairs.
Tools Required: Socket set, multimeter, OBD-II scanner, flathead screwdriver.

2. Check and Replace Fuse

Locate the fuse box, typically under the dashboard or in the front trunk area.
Remove the cover and identify the wiper fuse using the diagram on the cover.
Use a fuse puller or flathead screwdriver to remove the fuse.
Inspect the fuse; replace it if blown (use the same amperage rating as indicated).
Reinstall the fuse and cover, then reconnect the battery.

3. Inspect and Test Wiper Motor

Remove the wiper arms using a socket set (usually a 13mm socket); gently lift them off the splines.
Locate the wiper motor, typically mounted near the base of the windshield.
Disconnect the wiring harness from the motor.
Using a multimeter, test the motor by applying direct battery voltage to the motor terminals.
- If the motor operates, it is functional. If not, replace the motor.
Reinstall the motor and wiper arms.

4. Clean or Replace Wiper Blades

Inspect the wiper blades for wear or damage.
If damaged, replace them with new wiper blades compatible with Tesla Model 3.
Clean the windshield and the wiper blade rubber with a mild detergent to ensure proper contact.

5. Inspect Wiper Fluid System

Check the fluid reservoir for any leaks or clogs.
Remove and clean the spray nozzles with a pin if clogged.
Refill the reservoir with the recommended washer fluid.
