How to Replace Fuses of Infiniti QX80

  1. Locate the Fuse Box: The fuse box in the Infiniti QX80 is typically located inside the cabin, often beneath the dashboard on the driver’s side. Some models may have additional fuse boxes in the engine bay. Look for a panel labeled “Fuse” or “Fuses” to access it.

  2. Turn Off the Vehicle: Ensure that the vehicle’s ignition is turned off, and remove the key from the ignition switch to prevent electrical mishaps.

  3. Identify the Blown Fuse: Using a flashlight, carefully examine the fuses inside the fuse box. Look for any fuses with a broken wire or a discolored appearance, indicating that they have blown.

  4. Select a Replacement Fuse: Choose a replacement fuse with the same amperage rating as the blown fuse. Using a fuse with a different rating could cause electrical issues or damage to your vehicle.

  5. Remove the Blown Fuse: Use a fuse puller tool or a pair of needle-nose pliers to grip the blown fuse firmly. Pull the fuse straight out of its socket, taking care not to damage the fuse box or adjacent fuses.

  6. Insert the Replacement Fuse: Place the replacement fuse into the empty socket in the fuse box. Ensure it is seated securely and fully inserted to establish proper electrical connection.

  7. Check for Proper Fit: Double-check that the replacement fuse fits snugly into the socket and is of the correct amperage rating. It should not be loose or protruding from the socket.

  8. Replace the Fuse Box Cover: Once the blown fuse is replaced, carefully reattach the fuse box cover and ensure it is securely fastened to prevent debris from entering.

  9. Test the Circuit: Turn the ignition key to the accessory position or start the vehicle to test the circuit associated with the replaced fuse. Verify that the electrical component or system is functioning correctly.

  10. Dispose of the Blown Fuse: Dispose of the blown fuse properly. You can keep it as a spare in case of future emergencies or dispose of it according to local regulations for electronic waste.

Helpful Tips:

  • Use the fuse puller tool if provided with your vehicle to avoid damaging the fuse or fuse box.
  • Check other fuses if you find one blown fuse, as multiple fuses may blow simultaneously due to the same issue.
  • Keep spare fuses of various amperage ratings in your vehicle’s glove compartment for quick replacements during emergencies.
  • If you’re unsure about replacing a fuse or if the issue persists after replacement, consider consulting a certified Infiniti technician for assistance. They can diagnose and repair any underlying electrical problems in your Infiniti QX80.
