Fuse Box - Interior

This procedure covers the removal and replacement of the interior fuse box on a 2025 Rivian EDV 500, including disconnecting the high-voltage battery system and accessing the fusebox mounted in the driver-side footwell area.

Warnings

Tools required

Parts

• Interior fuse box assembly × 1 — Use OEM specification
• Push-pin retainers for trim panels × 10 — Various sizes as needed

Preparation

1. Park vehicle on level surface and engage parking brake
2. Ensure vehicle is powered off completely and remove key fob from cabin
3. Open driver-side door and leave open for duration of repair
4. Access the HV battery disconnect procedure through the vehicle's maintenance mode if equipped
5. Disconnect the 12V auxiliary battery negative terminal located in the front trunk compartment
6. Wait minimum 5 minutes for high-voltage system capacitors to fully discharge
7. Put on insulated gloves rated for high-voltage EV work

Procedure

1. 1

   Remove driver-side lower dash trim panel
   Using plastic trim removal tools, carefully pry out the lower dash panel below the steering column. Start at the bottom edge and work around the perimeter. Remove approximately 6-8 push-pin retainers. Disconnect any electrical connectors for footwell lighting if equipped.
2. 2

   Remove driver-side kick panel
   Locate and remove the kick panel on the driver-side footwell area. Remove 3 T20 Torx screws along the top edge and pull the panel away from the body. This exposes the side mounting area of the interior fuse box.
3. 3

   Verify HV system isolation
   Using a multimeter, verify that there is no voltage present at the HV disconnect point and that the 12V system shows no voltage at the fuse box terminals. Check the vehicle display for any high-voltage warnings. Do not proceed if voltage is detected.
4. 4

   Document fuse configuration
   Photograph or document all installed fuses and their positions in the interior fuse box. Note any empty slots and the amperage ratings of each fuse. This will be critical for proper reassembly.
5. 5

   Disconnect main harness connectors
   Locate the three main wiring harness connectors on the back of the interior fuse box. Press the locking tabs and carefully disconnect each connector. The connectors are color-coded: gray (body systems), black (powertrain control), and brown (accessory circuits). Label each connector for reinstallation.
6. 6

   Remove fuse box mounting fasteners
   Remove the four T30 Torx bolts securing the interior fuse box to the mounting bracket. Two bolts are located at the top of the assembly, and two are accessed from the side through the kick panel opening. Support the fuse box while removing the final fastener.
7. 7

   Remove interior fuse box assembly
   Carefully maneuver the interior fuse box out of the mounting location. The assembly must be tilted slightly and rotated to clear the steering column and pedal assembly. Avoid snagging wiring harnesses during removal.
8. 8

   Transfer fuses to new fuse box
   If replacing the fuse box, transfer all fuses from the old unit to the new unit in their exact positions using your documentation from Step 4. Ensure each fuse is fully seated and the correct amperage rating is in each position.
9. 9

   Install new or repaired fuse box
   Position the fuse box assembly into the mounting location, reversing the removal process. Align the mounting holes with the bracket and ensure no wiring is pinched behind the unit.
10. 10

    Install mounting fasteners
    Install the four T30 Torx mounting bolts and tighten in a cross pattern to ensure even seating. Tighten securely but do not overtorque as the mounting bracket is plastic-reinforced.
11. 11

    Reconnect wiring harness connectors
    Reconnect the three main harness connectors to the back of the fuse box in their correct positions (gray, black, brown). Ensure each connector clicks fully into place and the locking tabs engage properly.
12. 12

    Reconnect 12V auxiliary battery
    Return to the front trunk compartment and reconnect the negative terminal to the 12V auxiliary battery. Tighten the terminal connection securely.

Reassembly

1. Reinstall the driver-side kick panel and secure with the 3 T20 Torx screws
2. Reconnect any footwell lighting connectors if equipped
3. Reinstall the lower dash panel and press all push-pin retainers firmly into place
4. Verify all trim panels are secure and properly aligned with no gaps

Verification

• Power on the vehicle and verify the instrument cluster illuminates without error messages
• Check that all electrical systems operate correctly: lights, wipers, HVAC, infotainment, power windows
• Verify the high-voltage system initializes properly and shows ready status on the display
• Test drive the vehicle to confirm all drive systems and driver assistance features function normally
• Use the Rivian diagnostic system or app to scan for any stored fault codes related to electrical systems
• Recalibrate any systems as prompted by the vehicle display, including driver profiles or seat memory settings
