Tesla horns, while functional, might not always meet every owner's preference. Perhaps you crave a louder, more assertive sound, or maybe you simply need to replace a faulty horn. This guide will walk you through changing your Tesla horn, regardless of whether you drive a Model S, 3, X, or Y.

What You'll Need

Before you begin, gather these essential tools and parts:

New Tesla Horn: Ensure you purchase a horn compatible with your Tesla model. Check your owner's manual or online resources for the correct part number. Aftermarket options are available, offering different sounds.
Torque Wrench: Crucial for tightening bolts to the manufacturer's specified torque. Over-tightening can damage components.
Socket Set: You'll need sockets of various sizes. Consult your owner's manual for the exact sizes required for your model.
Phillips Head Screwdriver: Possibly needed depending on your Tesla model and horn type.
Jack and Jack Stands (Recommended): Lifting the front of your Tesla improves access and safety. Always use jack stands for stability and never work under a vehicle supported only by a jack.
Gloves: Protect your hands from grease and potential cuts.
Safety Glasses: Eye protection is essential for any automotive repair.

Step-by-Step Horn Replacement Guide

Disclaimer: This guide provides general instructions. Specific steps may vary slightly depending on your Tesla model year and trim level. Always consult your owner's manual for model-specific information. If you are uncomfortable performing this repair, take your vehicle to a qualified mechanic.

Step 1: Preparation

Park your Tesla on a level surface and engage the parking brake.
Disconnect the Tesla's 12V battery negative terminal. This prevents accidental short circuits.

Step 2: Accessing the Horn

Locate the horn. The exact location varies by model. Consult your owner's manual or online resources (like YouTube videos) for precise location details specific to your Tesla model. Generally, it's located in the front bumper area.
If necessary, use a jack and jack stands to lift the front of your vehicle for easier access. Always prioritize safety.

Step 3: Removing the Old Horn

Carefully disconnect the electrical connectors from the old horn. Take photos before disconnecting anything to ensure correct reassembly.
Use the appropriate sockets and wrenches to remove the mounting bolts securing the horn. Note the order and position of these bolts for proper reassembly.

Step 4: Installing the New Horn

Attach the new horn to its mounting location, ensuring it's securely fastened with the correct torque. Use your torque wrench to avoid over-tightening.
Carefully reconnect the electrical connectors to the new horn, matching them to their corresponding positions as noted in the photos you took earlier.

Step 5: Testing and Reassembly

Lower your Tesla (if you used a jack).
Reconnect the 12V battery negative terminal.
Test the new horn. If it doesn't work, double-check all connections.
If everything works, you are done!

Troubleshooting

Horn doesn't work: Verify all connections are secure and correctly matched. Check the horn fuse in the fuse box.
Horn sounds weak: This could indicate a problem with the electrical system or a faulty new horn.
