Step-by-Step Guide to Replacing Tesla Model 3/Y Taillights

Step 1: Preparing Your Vehicle

1. Disconnect the Power Supply: Open the trunk and disconnect the vehicle’s power supply to prevent any electrical accidents. This is crucial for your safety during the replacement process.

2. Organize the Trunk:Clear out the trunk to create ample workspace. Removing unnecessary items will make the process more efficient.

Step 2: Removing the Old Taillights

1. Detach the Trunk Liner: Use a trim removal tool to carefully detach the trunk liner, exposing the back of the taillights.

2. Remove the Dust Cover: Locate and remove the dust cover from the back of the taillights. This will allow access to the wiring and mounting points.

3. Disconnect the Wiring Harness: Identify the wiring harness connected to the taillights and disconnect it carefully. This may involve unclipping or unscrewing certain components.

4. Remove the Taillight Bolts: Use a ratchet and socket set to remove the bolts securing the taillights. Once the bolts are removed, gently extract the taillights from their positions.

Step 3: Installing the New Taillights

1. Position the New Taillights: Align the new taillights with the mounting points on the vehicle, ensuring they are correctly positioned.

2. Secure the Taillights: Use the ratchet and socket set to fasten the new taillights with the bolts. Make sure they are securely attached to avoid any movement.

3. Reconnect the Wiring Harness: Connect the wiring harness to the new taillights. Ensure all connections are secure and there are no loose wires.

4. Reinstall the Dust Cover: Place the dust cover back over the wiring and mounting points to protect them from debris.

5. Reattach the Trunk Liner: Once the new taillights are installed, reattach the trunk liner using the trim removal tool.

Step 4: Testing the New Taillights

1. Reconnect the Power Supply: Reconnect the vehicle’s power supply and test the new taillights to ensure they function correctly. Check the turn signals, brake lights, and reverse lights.

2. Inspect for Issues: Look for any signs of improper installation or malfunction. If everything is in order, you have successfully replaced your Tesla Model 3/Y taillights.

Tips for Preventing Taillight Fogging

Taillight fogging is a common issue caused by high humidity, leading to condensation inside the taillights. To prevent this, follow these tips:

• Keep the Taillights On: After installation, leave the taillights on for about 15 minutes to evaporate any moisture inside.

• Regular Maintenance: Periodically check the taillights for any signs of condensation and address it promptly.
