2021 Alfa Romeo Giulia Fuses and Fuse Box
In the 2021 Alfa Romeo Giulia, there are a lot of different electrical systems that power and control different parts of the car. Fuses are an important safety feature that keeps these systems from getting damaged by stopping overloads and electrical faults. Inside the Giulia’s fuse box, which was carefully made, are a number of small but important parts that are ready to protect against electrical problems that could otherwise affect the car’s performance or, in the worst cases, put safety at risk. This guide dives into the world of fuses and the fuse box in the 2021 Alfa Romeo Giulia. It explains how important they are to the reliability, safety, and usefulness of the car and gives tips on how to keep it in good shape and fix problems.
Fuses
GENERAL INFORMATION
WARNING
- When replacing a blown fuse, always use an appropriate replacement fuse with the same amp rating as the original fuse. Never replace a fuse with another fuse of a higher amp rating. Never replace a blown fuse with metal wires or any other material. Do not place a fuse inside a circuit breaker cavity or vice versa. Failure to use proper fuses may result in serious personal injury, fire, and/or property damage.
- Before replacing a fuse, make sure that the ignition is off and that all the other services are switched off and/or disengaged.
- If the replaced fuse blows again, contact an authorized dealer.
- If a general protection fuse for safety systems (air bag system, braking system), power unit systems (engine system, transmission system), or steering system blows, contact an authorized dealer.
The fuses protect electrical systems against excessive current. When a device does not work, you must check the electrical circuit inside of the fuse for a break/melt. Also, please be aware that using power outlets for extended periods of time with the engine off may result in vehicle battery discharge.

Fuse Extracting Pliers
To replace a fuse, use the pliers hooked to the fuse box. 
Grab the pliers from the upper tabs, press them, and extract the pliers pulling upwards. The pliers have two different ends, both of which are specifically designed to remove the different types of fuses present in the vehicle:
Fuse Extracting Pliers
- MINI fuse
- J-CASE fuse
After use, return the pliers to their proper position by following the below procedures:
- Grab the pliers from the upper tabs and insert them into their housing.
- Push downward on the pliers into their housing until they click into place.
FUSE LOCATION
The fuses, which can be replaced by the user, are grouped in two boxes below the passenger side footboard and inside the trunk.
CONTROL UNIT UNDER PASSENGER SIDE FOOTBOARD
To access the fuses, proceed as follows:
- Lift the upper end of the footboard on the passenger side, pulling to release the two buttons.
- Unscrewing the two hooks, remove the panel pulling downward.
The fuses are freely accessible on the control unit. After replacing the fuse, make sure that the panel and footboard are correctly locked.
LUGGAGE COMPARTMENT FUSE BOX
To access the fuses, proceed as follows:
- Lift the luggage compartment cover.
- Remove the control unit cover.
The fuses are freely accessible on the control unit. The number identifying the electrical component corresponding to each fuse is shown on the cover. After replacing a fuse, make sure that you have closed the cover correctly.
CONTROL UNIT UNDER PASSENGER SIDE FOOTBOARD
UNDER HOOD POWER DISTRIBUTION CENTER (PDC)
To access the fuses, remove the access door that is located under the hood on the left side rear.
To remove fuse cover, remove the screws with a suitable tool.
