If a fuse blows
Replacing the fuses When an electrical device is not functioning, check that the corresponding fuse is in proper working order.
A – Fuse intact.
B – Blown fuse. 
Replace the faulty fuse with a new one having the same rating (same colour). If the fault recurs, consult the Maserati Service Network. Never replace a blown fuse with anything other than a sound fuse having the same rating/colour.

- on the right-hand side of the luggage compartment;
- behind the glove compartment, to the left of the steering wheel;
- in the luggage compartment next to the battery, in the spare wheel housing.

How to replace a Fuse in the 2017 Maserati Grancabrio
- Locate the Fuse Box:
- The fuse box in the Maserati Grancabrio is usually located in one of several places.
- Identify the Blown Fuse:
- Inspect the fuses to determine which one is blown. A blown fuse will typically have a broken wire inside or will appear burnt.
- Disconnect the Battery
- Before working on the electrical system, it’s essential to disconnect the car battery to avoid any risk of electrical shock or damage.
- Remove the Blown Fuse:
- Using a fuse puller tool or a pair of needle-nose pliers, carefully remove the blown fuse from its slot. Be gentle to avoid damaging the fuse or the fuse box.
- Replace with a New Fuse:
- Insert a new fuse of the same rating into the slot. Make sure the fuse is securely in place.
- Reconnect the Battery:
- Once you’ve replaced the fuse, reconnect the car battery.
- Test the Circuit:
- Turn on the ignition and test the circuit to ensure that the new fuse is functioning correctly. If the circuit works as expected, you’ve successfully replaced the fuse.
- Dispose of the Blown Fuse:
- Dispose of the blown fuse safely. If it’s a glass fuse, wrap it in paper and dispose of it in the trash. If it’s a blade-type fuse, you can recycle it if facilities are available in your area.
- Close the Fuse Box:
- Once everything is working correctly, close the fuse box cover if applicable.
