How to Change the Horn on a Tesla: Step-by-Step Guide
All Teslas come with an electric stock horn that is enough for everyday driving. However, some Tesla owners don't find this horn to be loud enough, or want something more personal. If you’re one of these Tesla owners, you have probably thought about changing your horn for another. Whether you want a louder horn for safety reasons, or you just to make your car stand out, you can easily replace the stock horn in your Tesla.
However, to ensure your safety and to avoid any damage to the car, it is important to know the steps to take. In this article, we will take you through the step-by-step method of swapping your Tesla's horn.
Why Change Your Tesla's Horn?
The Tesla company takes prides in its innovations. That is why they design all their vehicles with advanced safety features. However, the factory-installed horn is often described as too soft or unassertive, especially in serious traffic. That is why several Tesla owners usually try to upgrade the horn after purchase.
If you’ve been thinking about changing your Tesla horn, here are some reasons why you should:
● Better Road Presence: Having a louder horn ensures that surrounding drivers notice you, especially on busy roads. That way you will be able to alert other road users on time.
● Personalization: Tesla horns have a default sound across all models. That means if you want to personalize the sound of your horn, you need to change it. A new horn allows you to decide your vehicle's personality.
● Emergency Situations: A loud horn can alert distracted drivers and pedestrians better. If you happen to be in an emergency situation and you need to alert a civilian or other road users, a good horn can help you here.
● Durability: Some replacement horns last longer and withstand harsher weather conditions better than stock options. Hence, some people prefer to change their vehicle horns with these longer-lasting models.
Tesla owners can upgrade other parts of their cars as well, such as Tesla Model Y parts, Tesla Model X parts, or even center console covers. This can enhance both functionality and aesthetics. You can visit our website for any Tesla parts you need.
Tools and Materials Needed
Before you can replace the horn, you need to get some tools. Having the right tools close by will make the installation smoother. Here are some of the tools you will need:
● Compatible replacement horn: Make sure the replacement horn is compatible with your Tesla model.
● Socket wrench set: You will need a wrench set with 10mm and 15mm sockets.
● Trim removal tool or plastic pry tool: You will need this to safely remove panels.
● Phillips screwdriver: This is to remove screws
● Electrical connectors: You might need this to make wiring adjustments.
● Insulated gloves: This is for safety when handling electrical components.
Some replacement horns may require additional wiring when installing them. Hence, you should check the product specifications before starting to make sure.
Step 1: Powering Off the Vehicle for Safety
Tesla’s electrical system is complex and carries a high voltage. Therefore, safety should be your top priority. The first step to take when replacing your horn is to turn off the vehicle completely. Follow these steps to properly shut down your Tesla before working on the horn:
- Enter Service Mode: On your Tesla touch-screen, go to Service > Power Off. This will turn off your Tesla and prevent any accidental electrical surges.
- Disconnect the Battery: Open the front of the car and locate the battery (varies by model). After that, remove the negative (-) terminal using a wrench. Usually after you do this, the Tesla will be completely off.
- Disable the High-Voltage System (if applicable): Some models, like the Model S and X, may require you to disconnect the first responder loop. This is like a high-voltage system that turns on by itself.
Please ensure you do not skip this step! Tesla’s electrical components can be dangerous if the system is live while working on them. To prevent any electrical accidents, make sure the vehicle is shut down completely before starting.
Step 2: Locating the Horn in Your Tesla Model
The horn of a Tesla can be located in different areas of the vehicle, depending on your model. Here’s a little breakdown:
● Tesla Model 3 & Model Y: The horn for these models is located behind the front trunk liner. This makes it relatively easy to access.
● Tesla Model S & Model X: In these models, the horn is behind the front bumper. Therefore, you will need a partial bumper removal before you can take it out.
To access the horn of the Model 3 & Model Y:
- Open the front trunk and remove any stored items.
- Use a trim removal tool to carefully detach the plastic front trunk liner.
- Locate the horn assembly near the front center of the vehicle.
To access the horn of the Model S & Model X:
- Remove the undercarriage bolts and loosen the front bumper clips.
- Partially pull the bumper forward to expose the horn.
Tesla’s modular design makes it easy to remove it's panels. However, it is still better to be gentle to avoid damaging any of the clips and connectors.
Step 3: Removing the Old Horn
Once you’ve located the horn, the next thing to do is remove the old one from the vehicle. To do this, you need to:
- Unplug the electrical connector: Press the release tab and gently pull out the electrical connector.
- Remove the mounting bolt: Use a socket wrench to unscrew the bolt securing the horn. After removing the bolt, you can take out the horn.
- Inspect the wiring: Check for burnt or damaged wires before installing the new horn. This is to avoid any electrical problems later.
Step 4: Installing the New Horn
Installing a new horn in your Tesla is very simple. You just need to pay proper attention to positioning and secure wiring. To install the new horn into your car, follow these steps:
- Mount the new horn in the same location as the original horn.
- Secure it using the mounting bolt and ensure it is tightly fastened to prevent vibrations.
- Connect the electrical wiring
- Double-check the alignment to ensure the horn is positioned correctly.
Some replacement Tesla parts, such as Tesla hub assemblies, come with upgraded wiring harnesses that offer better connectivity.
Step 5: Testing the New Horn
Before reassembling your car, it is best to test the new horn you just installed. This is to ensure it works properly. Here’s how you can test the horn without re-assembling the Tesla:
- Reconnect the battery and power the Tesla back on.
- Press the horn button on the steering wheel to check the way the sound is.
- If you find any issues, Troubleshoot them:
If the horn doesn’t work after reconnecting the battery, check the wiring connections again to make sure there weren’t any errors. If the sound of the horn is too low, ensure it is mounted correctly. Also ensure that nothing is obstructing it, as this can cause the sound to appear muffled. You can also use additional soundproofing to enhance the acoustics of the new horn.
Step 6: Reassembling the Vehicle
Once you have confirmed that the new horn is functioning correctly, you can begin to reassemble the panels. Just retrace the steps you took when dismantling the pieces in the first place:
- Reattach the liner in the trunk (Model 3 & Y) or the bumper (Model S & X).
- Secure all screws and clips to prevent rattling.
- Check the alignment of the panels and ensure they fit seamlessly for good aesthetics and functional integrity.
Teslas are designed with precision, so take your time ensuring everything is properly reassembled. This is to prevent any unexpected errors happening later on. If even a single part of the dismantled pieces is missing or not placed properly, it can reduce the aesthetics or performance of the car.
