Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and turned off.
Disconnect the vehicle's 12V battery to prevent electrical shock.

2. Check and Replace the Fuse

Locate the fuse box in the front trunk (frunk) of the Tesla Model 3.
Refer to the owner's manual to identify the fuse associated with the windshield wipers.
Remove the fuse using a fuse puller and inspect it for continuity.
If blown, replace it with a new fuse of the same amperage rating.

3. Inspect and Repair Wiring Connections

Reconnect the battery to power the vehicle.
Access the wiper motor by removing any necessary covers or components.
Visually inspect the wiring harness connected to the wiper motor for damage.
If any corrosion or damage is found, repair or replace the affected wires.

4. Test the Wiper Motor

Disconnect the wiper motor plug.
Using a multimeter, check for voltage at the connector when the wiper switch is activated.
If no voltage is present, further diagnose the switch and circuit.
If voltage is present, apply direct voltage to the motor to see if it operates.

5. Replace the Wiper Motor (if necessary)

If the motor does not operate with direct voltage, it may need replacement.
Remove the wiper arm assembly by unscrewing the retaining nut and pulling the arm off the spindle.
Unbolt the motor from its mount and disconnect the wiring harness.
Install the new motor by reversing the removal steps, ensuring all connections are secure.
