2015 Tesla Model X Fuse Box Diagram & Amperage

Quick Answer

The 2015 Tesla Model X features multiple fuse box locations to protect its complex electrical systems. You'll find fuse boxes located in the front trunk (frunk), under the dashboard on the passenger side, and in the rear cargo area.

Front Trunk (Frunk) Fuse Box

The frunk fuse box primarily houses fuses and relays for high-current components and critical vehicle systems. Always refer to the printed diagram on the fuse box cover for the most accurate information for your specific trim level.

Passenger Side Dash Fuse Box

This fuse box, often located behind a kick panel or glove box access panel on the passenger side, typically protects interior electrical components and accessories.

Rear Cargo Area Fuse Box

Located in the rear cargo area, often behind a trim panel on the side, this fuse box handles power distribution for rear vehicle functions, convenience features, and potentially trailer-related circuits.

How to Test a Fuse

1. Locate the fuse box: Refer to the Quick Answer section above to find the correct fuse box for the circuit you're troubleshooting.
2. Identify the suspected fuse: Use the tables or the diagram on the fuse box cover to find the fuse for the component that isn't working.
3. Visual inspection: Many fuses have a visible wire inside. If this wire is broken or melted, the fuse is blown. However, not all blown fuses are visually obvious, especially with mini or low-profile fuses.
4. Use a fuse tester or multimeter:
   • Fuse Tester: A simple fuse tester lights up if the fuse is good. Simply touch the probes to the test points on top of the fuse (or remove it and test it directly).
   • Multimeter: Set your multimeter to measure continuity (Ω or "beep" setting). With the fuse removed from its slot, touch the probes to each metal blade of the fuse. A good fuse will show continuity (a very low resistance reading or a beep). A blown fuse will show no continuity (an open circuit or "OL").
5. Always replace a blown fuse with one of the exact same amperage rating and type. Using a fuse with a higher amperage can cause severe electrical damage or even a fire.

Common Blown Fuses on This Vehicle

While the Tesla Model X is a sophisticated vehicle, certain fuses may be more prone to blowing due to common usage or specific component demands. If you experience an electrical issue, here are some common areas to check first:

• 12V Outlets / USB Ports: These fuses (e.g., Passenger Side Dash F2, F17, Rear Cargo F6) can blow if too many high-draw devices are plugged in, or if a faulty charger or accessory is used. If your phone isn't charging, check these first.
• Headlights / Tail Lights: While less common with LED lighting, a fuse related to a headlight or taillight (e.g., Frunk F5, F6, F7, F8, Rear Cargo F1, F2, F3) can blow, especially if there's a wiring issue or a faulty control module affecting the circuit. If a single light unit is out, this could be the culprit.
• Blower Motor: The blower motor fuse (e.g., Passenger Side Dash F3) can blow due to a failing motor drawing too much current, debris obstructing the blower, or a resistor pack issue. If your A/C or heat isn't blowing air, this is a good place to start.
• Windshield Washer Pump / Wiper Motor: These components (e.g., Frunk F10, F11, F15, Passenger Side Dash F15) are exposed to the elements and frequent use. A seized pump or motor, or even a short in the wiring, can cause their fuses to blow. If your wipers or washers stop working, check these.
• Trailer Brake Controller: If your Model X is equipped with a tow package and you're experiencing issues with trailer brakes, check the dedicated fuse in the rear cargo area (Rear Cargo F8). Overloading or a short in the trailer wiring can cause this to blow.

When troubleshooting, always begin by checking the most obvious and easily accessible fuses. If a fuse repeatedly blows, it indicates a deeper electrical problem that needs professional diagnosis. Do not try to bypass a fuse or replace it with a higher-rated one.
