Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is in a safe, flat area with the ignition off.

2. Inspect and Replace Fuse

Tools Required: Fuse puller or pliers
Locate the fuse box (usually under the dash or in the frunk).
Identify and remove the wiper fuse (refer to the owner's manual for the exact fuse location).
Inspect the fuse for continuity; replace if blown with the same amperage rating.

3. Test Wiper Motor and Wiring

Tools Required: Multimeter
Disconnect the wiper motor connector.
Use a multimeter to check for voltage at the motor connector when the wiper switch is activated.
If voltage is present, the motor may be faulty; proceed to replace it.

4. Replace Wiper Motor (if necessary)

Tools Required: Socket set, screwdrivers
Remove any covers concealing the wiper motor.
Unscrew the motor from its mounting bracket.
Disconnect the wiring harness and remove the motor.
Install the new motor by reversing the removal steps and ensure all connections are secure.

5. Reassemble and Check Functionality

Reconnect any covers removed during the process.
Reinsert the fuse if it was removed.
Power on the vehicle and test the wipers for proper function.
