Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is off and parked on a level surface.
Disconnect the negative battery terminal for safety.

2. Fuse Replacement

Locate the fuse box in the Tesla Outback, typically under the dashboard or in the engine compartment.
Identify the windshield wiper fuse using the fuse diagram.
Remove the fuse using a fuse puller or pliers.
Inspect the fuse for continuity; if blown, replace it with a new fuse of the same amperage (usually 15A).

3. Wiper Switch Inspection

Reconnect the battery temporarily to test the wiper switch.
Activate the wiper switch and use a multimeter to check for continuity at the switch terminals.
If there is no continuity, replace the wiper switch.

4. Wiper Motor Testing

Disconnect the wiring harness from the wiper motor.
Using jumper wires, connect the motor directly to the battery to check for operation.
If the motor does not run, replace the wiper motor.

5. Wiring Inspection

Visually inspect the wiring harness for any signs of wear, fraying, or disconnections.
Repair or replace damaged wiring as needed to ensure proper electrical connection.
