Front Trunk (Frunk) Fuse Box

The front trunk fuse box primarily houses fuses for critical powertrain components, lighting, and some vehicle control modules. Always refer to the fuse diagram on the fuse box cover for the most accurate and up-to-date information for your specific vehicle configuration.

Fuse #	Amp	Color	Circuit / Component Protected
F1	10A	Red	Powertrain Control Module (PCM) - Main
F2	5A	Tan	Powertrain Control Module (PCM) - Sensors
F3	20A	Yellow	Headlight (Low Beam) - Left
F4	20A	Yellow	Headlight (Low Beam) - Right
F5	15A	Blue	Headlight (High Beam) - Left
F6	15A	Blue	Headlight (High Beam) - Right
F7	10A	Red	Ignition System
F8	30A	Green	Blower Motor - HVAC
F9	25A	Clear	ABS Pump Motor
F10	10A	Red	ABS Module
F11	15A	Blue	Air Conditioning (A/C) Clutch (if applicable)
F12	10A	Red	Front Wiper Motor

Relays in the Frunk Fuse Box:

• R1: Main Powertrain Relay
• R2: Headlight Low Beam Relay
• R3: Headlight High Beam Relay
• R4: Blower Motor Relay

Passenger Side Dashboard Fuse Box

This fuse box, often located behind a panel under the dashboard on the passenger side, typically protects interior electronic components, infotainment systems, and convenience features.

Fuse #	Amp	Color	Circuit / Component Protected
F1	5A	Tan	Instrument Cluster
F2	10A	Red	Radio/Infotainment System - Main
F3	15A	Blue	USB Charging Ports
F4	20A	Yellow	12V Power Outlet (Cigar Lighter) - Front
F5	10A	Red	Airbag Control Module
F6	5A	Tan	Occupant Classification System
F7	15A	Blue	Power Door Locks
F8	10A	Red	Interior Lighting
F9	5A	Tan	Power Window - Passenger Front
F10	5A	Tan	Power Window - Passenger Rear
F11	10A	Red	HVAC Control Module
F12	7.5A	Brown	Mirror Adjustments

Relays in the Passenger Side Dashboard Fuse Box:

• R1: Accessory Power Relay
• R2: Power Window Relay - Passenger Front

Rear Cargo Area Fuse Box

The fuse box in the rear cargo area protects circuits for rear lighting, rear accessories, and components often found in the trunk or cargo space, and potentially trailer brake systems if equipped.

Fuse #	Amp	Color	Circuit / Component Protected
F1	10A	Red	Tail Lights - Left
F2	10A	Red	Tail Lights - Right
F3	5A	Tan	Park Lights - Left
F4	5A	Tan	Park Lights - Right
F5	15A	Blue	Brake Lights
F6	20A	Yellow	12V Power Outlet (Cigar Lighter) - Rear/Cargo
F7	10A	Red	Rear Wiper Motor (if equipped)
F8	20A	Yellow	Trailer Brake Control Module (if equipped)
F9	15A	Blue	Rear Liftgate Motor
F10	25A	Clear	Amplifier (Premium Audio)

Relays in the Rear Cargo Area Fuse Box:

• R1: Rear Accessory Power Relay
• R2: Trailer Brake Relay (if equipped)

How to Test a Fuse

Testing a fuse is a straightforward process that can help diagnose electrical issues. You'll need a fuse puller (usually found in one of the fuse boxes) and a multimeter or a fuse tester.

1. Locate the Fuse Box: Identify the correct fuse box for the circuit you're troubleshooting.
2. Refer to the Diagram: Consult the fuse diagram on the fuse box cover to pinpoint the fuse in question.
3. Remove the Fuse: Use the fuse puller to carefully remove the suspect fuse. Never use metal tools like pliers, as this can damage the fuse or cause a short circuit.
4. Visually Inspect: Many fuses are transparent, allowing for a quick visual check. If the metal wire or filament inside is broken or charred, the fuse is blown and needs replacement.
5. Test with a Multimeter: For less obvious cases, set your multimeter to the continuity setting (usually indicated by a sound wave symbol). Touch one probe to each metal terminal on the fuse. If you hear a beep or the display shows a very low resistance (0-1 ohm), the fuse is good. If there's no beep or the display shows "OL" or "infinite resistance," the fuse is blown.
6. Replace the Fuse: If the fuse is blown, replace it with a new fuse of the exact same amperage and type. Using a fuse with a higher amperage can lead to serious electrical damage or fire.
7. Reinstall Fuse Box Cover: Ensure the fuse box cover is securely reinstalled to protect the fuses from dirt and moisture.

Common Blown Fuses on This Vehicle

Due to the advanced electrical architecture of the Tesla Model X, certain fuses might be more prone to blowing depending on usage and accessory load. While specific common blown fuses can vary, here are some general areas to check first:

• 12V Power Outlets (Cigar Lighter): These outlets are frequently used for charging various devices, and overloads from high-power accessories or faulty device chargers can cause these fuses to blow. If your phone charger or other accessories stop working in the 12V outlets, check the corresponding fuses (e.g., F4 in the Passenger Side Dashboard, F6 in the Rear Cargo Area).
• Infotainment/Radio System: Issues with aftermarket accessories or even internal software glitches can sometimes cause the infotainment system fuse to blow. If your screen or audio system is unresponsive, check the main infotainment fuse (e.g., F2 in the Passenger Side Dashboard Fuse Box).
• Headlights/Exterior Lighting: While less common in modern vehicles with LED lighting, a short circuit or an internal fault in a lighting component can still blow a fuse. If a specific headlamp or tail lamp isn't working, check its dedicated fuse (e.g., F3, F4, F5, F6 in the Frunk Fuse Box, F1-F5 in the Rear Cargo Area Fuse Box).
• Accessory Fuses: With the increasing number of connected devices and charging demands, fuses for USB ports or other convenience outlets can sometimes blow due to excessive draw or shorted devices.

What to Check First:

When troubleshooting an electrical issue, always start by checking the fuses related to the non-functioning component. If a fuse is repeatedly blowing, there's a deeper underlying issue such as a short circuit, an overloaded circuit, or a faulty component that needs professional diagnosis.
