Quick Answer
The 2025 Tesla Model S features fuse boxes in the following locations: under the hood (front trunk or "frunk"), under the dashboard on the passenger side, and in the rear cargo area.
Under-Hood Fuse Box (Front Trunk - "Frunk")
The under-hood fuse box in your 2025 Tesla Model S is located in the front trunk area, typically on the passenger side beneath a plastic cover. This box houses fuses and relays for critical systems such as the powertrain, high-voltage contactors, and some auxiliary systems. Always verify the specific fuse layout against the diagram printed on the fuse box lid, as configurations can vary slightly by trim level.
| Fuse # | Amp | Color | Circuit / Component Protected |
|---|---|---|---|
| F1 | 10A | Red | ECM/PCM (Powertrain Control Module) |
| F2 | 15A | Blue | Ignition System |
| F3 | 50A | Red | High Voltage Contactor 1 |
| F4 | 50A | Red | High Voltage Contactor 2 |
| F5 | 10A | Red | Starter Relay (Control) |
| F6 | 30A | Green | ABS Pump Motor |
| F7 | 20A | Yellow | ABS Valve Solenoids |
| F8 | 15A | Blue | Headlight - Left Low Beam |
| F9 | 15A | Blue | Headlight - Right Low Beam |
| F10 | 10A | Red | Headlight - Left High Beam |
| F11 | 10A | Red | Headlight - Right High Beam |
| R1 | Starter Relay | ||
| R2 | ECM/PCM Main Relay | ||
| R3 | ABS Pump Relay |
Passenger Side Dashboard Fuse Box
This fuse box is typically found behind a panel on the passenger side of the dashboard, often requiring the panel to be carefully pried open. It usually controls various interior accessories and climate control components. Refer to your vehicle's owner's manual and the fuse box lid diagram for the most accurate information.
| Fuse # | Amp | Color | Circuit / Component Protected |
|---|---|---|---|
| F1 | 15A | Blue | Radio / Infotainment System |
| F2 | 20A | Yellow | Blower Motor |
| F3 | 10A | Red | A/C Clutch (if applicable) |
| F4 | 20A | Yellow | Cigar Lighter / 12V Power Outlet (Front) |
| F5 | 15A | Blue | Cabin Fuse Block Main Power |
| F6 | 7.5A | Brown | Airbag System (SRS) |
| F7 | 10A | Red | Interior Lights |
| F8 | 5A | Tan | Instrument Cluster |
| F9 | 15A | Blue | Power Windows - Front Left |
| F10 | 15A | Blue | Power Windows - Front Right |
| R1 | Blower Motor Relay | ||
| R2 | Accessory Power Relay |
Rear Cargo Area Fuse Box
The rear cargo area fuse box is generally located on one of the side panels in the trunk or cargo space, often behind a removable trim panel. This box typically handles power for rear accessories, tail lights, and sometimes charging port components.
| Fuse # | Amp | Color | Circuit / Component Protected |
|---|---|---|---|
| F1 | 10A | Red | Tail Lights - Left |
| F2 | 10A | Red | Tail Lights - Right |
| F3 | 15A | Blue | Brake Lights |
| F4 | 20A | Yellow | 12V Power Outlet (Rear Cargo) |
| F5 | 25A | Clear | Trailer Brake Controller (if equipped) |
| F6 | 10A | Red | Park Assist Sensors |
| F7 | 15A | Blue | Rear Wiper Motor (if equipped) |
| R1 | Trailer Power Relay (if equipped) |
How to Test a Fuse
Testing a fuse is a straightforward process that can save you a trip to the mechanic. Here
Before you pull a fuse on the 2025 Tesla Model S
- Use the label printed on the panel cover or the owner's manual for your exact build. Layouts change with options, model year and build date, so a chart for another truck can be wrong.
- Replace a blown fuse only with the same amp rating. A larger fuse can let wiring overheat.
- A fuse that blows again right away means a short or failing component downstream. Find the cause before replacing it again.
- A good fuse doesn't prove the circuit works — relays, grounds and connectors fail too.
- Disconnect the battery before working near high-current fuses or cables.
