2025 Tesla Model Y Fuse Box Diagram & Amperage

Quick Answer

The 2025 Tesla Model Y, being a fully electric vehicle, does not have a traditional internal combustion engine (ICE) with components like an ECM, fuel pump, or ignition system. Instead, its electrical system is managed by various electronic control units (ECUs) and power distribution modules. Fuse boxes are located in three primary areas:

• Front Under-Hood (Frunk): Located on the passenger side, typically beneath a plastic cover.
• Passenger Dash Kick Panel: Behind a removable panel on the passenger side of the dashboard.
• Rear Cargo Area (Trunk): On the left side, behind a removable panel.

Front Under-Hood Fuse Box

The under-hood fuse box primarily handles high-current circuits for major electrical systems and components. Due to the Model Y's electric nature, you won't find fuses for traditional ICE components. Always refer to the fuse diagram printed on the inside of the fuse box cover for the most accurate information for your specific vehicle configuration.

Fuse #	Amp	Color	Circuit / Component Protected
F1	40A	Green	Main Cabin Power Supply
F2	30A	Pink	Air Conditioning Compressor
F3	50A	Red	Drive Unit (Front/Rear) Power
F4	20A	Yellow	Power Steering
F5	15A	Blue	Headlight (Left)
F6	15A	Blue	Headlight (Right)
F7	10A	Red	Low Voltage DCDC Converter
F8	25A	Clear	ABS/ESC Module
F9	40A	Green	Main High Voltage Contactors
F10	10A	Red	Radiator Fan
F11	5A	Tan	Front Camera / ADAS
F12	15A	Blue	Horn

Relay Locations: Several relays are integrated into power distribution modules within the under-hood area, managing high-current circuits such as the main high-voltage contactors and the air conditioning compressor. Specific relay positions may vary; always consult the vehicle's service manual or the diagram on the fuse box cover.

Passenger Dash Kick Panel Fuse Box

This fuse box manages various interior electrical components and accessories. To access it, gently pry off the panel located on the passenger side, near the floorboard, below the glove compartment. Use a non-marring trim tool to avoid damage.

Fuse #	Amp	Color	Circuit / Component Protected
F1	5A	Tan	Infotainment System / Touchscreen
F2	15A	Blue	Power Windows (Passenger Front)
F3	10A	Red	Wiper Motor
F4	7.5A	Brown	USB Charging Ports
F5	20A	Yellow	12V Power Outlet (Front/Console)
F6	5A	Tan	Cabin Lights (Interior Illumination)
F7	10A	Red	HVAC Blower Motor Control
F8	15A	Blue	Seat Heaters (Passenger Front)
F9	5A	Tan	Airbag Control Module (SRS)
F10	10A	Red	Mirror Adjustments
F11	7.5A	Brown	Door Lock Actuators
F12	5A	Tan	Steering Wheel Controls

Relays: Relays for interior functions, such as power windows or the blower motor, are often integrated into the Body Control Module (BCM) or other electronic control units rather than being standalone, easily accessible units within this fuse box. Refer to the vehicle's service diagram for detailed relay information.

Rear Cargo Area Fuse Box

Located on the left side of the cargo area, behind a trim panel, this fuse box handles electrical circuits for the rear of the vehicle, including components like the rear lights, trailer connections, and other cargo-area accessories.

Fuse #	Amp	Color	Circuit / Component Protected
F1	10A	Red	Tail Lights (Left)
F2	10A	Red	Tail Lights (Right)
F3	15A	Blue	Trailer Brake (if equipped)
F4	20A	Yellow	Rear 12V Power Outlet
F5	5A	Tan	Rear Camera
F6	15A	Blue	Power Liftgate
F7	10A	Red	Rear Window Defroster
F8	7.5A	Brown	Trunk/Cargo Area Lights
F9	5A	Tan	Parking Assist Sensors (Rear)
F10	20A	Yellow	Rear Seat Heaters

Relays: Similar to the dash fuse box, relays for components in the rear of the vehicle, such as the power liftgate or trailer brake, are typically integrated into dedicated control modules. Consult the service manual for precise relay locations and functions.

How to Test a Fuse

Testing a fuse is a straightforward process that can help you diagnose electrical issues. You'll need a multimeter or a dedicated fuse tester.

1. Safety First: Ensure the vehicle is off and the parking brake is engaged. For a Tesla, it's also wise to engage the "Power Off" function in the settings menu to reduce the risk of accidental power delivery.
2. Locate the Fuse: Refer to the appropriate fuse box diagram (under the lid or in this guide) and identify the fuse suspected of being blown.
3. Visual Inspection: Carefully remove the fuse using the plastic fuse puller usually found in the fuse box or a pair of needle-nose pliers. Hold it up to the light. A good fuse will have a continuous wire link inside. A blown fuse will have a broken or melted wire.
4. Test with a Multimeter (Continuity Test):
   • Set your multimeter to the continuity setting (it usually looks like a diode symbol or an audible beep setting).
   • Touch one probe to each metal blade of the fuse. A good fuse will show a very low resistance (close to 0 ohms) or the multimeter will beep, indicating continuity. If the multimeter shows an open circuit (OL or infinity) or doesn't beep, the fuse is blown.
5. Test with a Fuse Tester: Insert the fuse into the fuse tester. The tester will typically light up if the fuse is good.
6. Replace if Blown: If the fuse is blown, replace it with a new fuse of the exact same amperage rating and type. Never use a fuse with a higher amperage rating, as this can lead to serious electrical damage or fire.

Common Blown Fuses on This Vehicle

While the 2025 Tesla Model Y is a highly advanced electric vehicle, certain fuses are more prone to blowing due to common usage or potential issues. Remember that "common" can vary with individual use and vehicle age.

• 12V Power Outlets (Cigar Lighters): These fuses (e.g., F5 in the Dash Kick Panel and F4 in the Rear Cargo Area) are frequently blown by using high-draw accessories or faulty charging devices. If your phone charger or air pump isn't working, this is the first place to check.
• USB Charging Ports: Similar to 12V outlets, overcurrent from faulty devices or improper charging can blow these fuses (e.g., F4 in the Dash Kick Panel).
• Infotainment System / Touchscreen: While less common, issues with the infotainment system (e.g., F1 in the Dash Kick Panel) can sometimes be traced to a blown fuse, especially after a software update or electrical anomaly. Always check for system reboots or software issues before assuming a blown fuse for the infotainment system.
• Trailer Brake (if equipped): If you frequently tow, the trailer brake fuse (e.g., F3 in the Rear Cargo Area) can blow if there's a short in the trailer's wiring or if the trailer brakes draw excessive current.

What to check first:

• Power Source: Before checking fuses for accessories like charging ports, ensure the vehicle is sufficiently charged and operating normally.
• Connected Devices: Disconnect any recently connected devices from 12V outlets or USB ports before checking the fuse, especially if the fuse blew immediately after plugging something in.
• Vehicle Settings: For issues with features like the liftgate or climate control, first check the vehicle's settings on the touchscreen to ensure they are enabled and configured correctly.
• Software Updates: Tesla vehicles receive over-the-air software updates. Sometimes, temporary glitches can occur after an update. A soft reset of the vehicle (refer to your owner's manual for instructions) can resolve many minor electronic issues without needing to check fuses.

Always verify the specific fuse layout and amperage for your 2025 Tesla Model Y using the diagram printed on the fuse box cover, as configurations can vary slightly due to market or optional equipment.
