how to check the fuses in my Tesla Model 3 Highland (2024-present)

Solution

1. Preparation

• Gather necessary tools: multimeter, fuse puller, and replacement fuses.
• Ensure the vehicle is turned off and parked safely.

2. Access the Fuse Box

1. Open the front trunk (frunk) by using the interior release button or the key fob.
2. Locate the fuse box cover on the driver's side beneath the dashboard.
3. Remove the fuse box cover by gently pulling it away from the clips.

3. Inspect and Test Fuses

1. Using the fuse diagram from the owner's manual, identify which fuses correspond to the non-functioning components.
2. Remove each fuse using the fuse puller to avoid damage.
3. Visually inspect each fuse for any signs of damage; if the filament is broken or the fuse appears burnt, it is blown.
4. Test each fuse with a multimeter set to the continuity setting. Place one probe on each end of the fuse. A beep indicates continuity (fuse is good), while no sound indicates a blown fuse.

4. Replace Blown Fuses

1. If a blown fuse is identified, refer to the owner's manual for the correct amperage rating for replacement.
2. Insert a new fuse of the same rating into the appropriate slot.
3. Ensure the fuse is seated properly in the fuse box.

5. Reassemble and Test

1. Replace the fuse box cover securely.
2. Close the front trunk (frunk).
3. Start the vehicle and test the previously malfunctioning components to confirm functionality.
