Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the ignition is off.
Disconnect the 12V battery to prevent electrical shorts.

2. Inspect and Replace Fuse

Locate the fuse box in the front trunk (frunk) of the Model Y.
Remove the cover and identify the wiper fuse (refer to the fuse diagram).
Pull the fuse using pliers and inspect it for continuity; replace it if blown.
Reinsert the fuse into its slot and replace the cover.

3. Check and Replace Wiper Motor

If the fuse is intact, locate the wiper motor (usually under the plastic cover at the base of the windshield).
Remove any screws or clips securing the cover and lift it off.
Disconnect the wiring harness from the wiper motor.
Use a socket wrench to remove the mounting bolts securing the motor, then carefully remove the motor.
Install the new wiper motor in the reverse order, ensuring all connections are secure.

4. Reassemble Components

Reattach the wiper arms if they were removed.
Replace the plastic cover over the wiper motor and secure it with screws or clips.
Reconnect the 12V battery and ensure all tools are removed from the engine bay.
