FUSES
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 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, trans-mission system) or steering system blows, contact an authorized dealer.
GENERAL INFORMATION
The fuses protect electrical systems against excessive current.
When a device does not work, you must check the fuse element inside the blade fuse for a break/melt. Also, please be aware that when using power outlets for extended periods of time with the engine off may result in vehicle battery discharge.
Blade Fuses
- Fuse Element
- Blade Fuse with a good/functional fuse element.
- Blade fuse with a bad/not functional fuse element (blown fuse).

FAQs
A vital part of a 2020 Fiat 500L, the fuse box contains the electrical fuses that guard the various electrical circuits in the car.
The fuse box is typically found in the passenger area, close to the dashboard on the driver’s side. If you’re unsure of where it is, see your owner’s manual.
When a circuit overloads, safety devices called fuses stop the flow of electrical current. They serve as a safeguard against electrical fires and component damage.
Check the fuse visually. The fuse blows if the interior metal wire breaks or melts. As an alternative, check for continuity with a multimeter.
The circuit will determine the size of the fuse. The right amperage ratings can be found on the fuse box cover or in your owner’s manual.
Remove the key and turn the ignition off. Fuse pullers or needle-nose pliers can be used to locate the blown fuse, remove it, and replace it with a new fuse of the same amperage.
The fuse box frequently comes with spare fuses, or you can buy them at an auto parts store. Get the appropriate amperage rating, please.
It’s not advised, so no. Using a higher amperage fuse may result in fires or damage to the electrical system. Use the proper amperage at all times.
A persistently blowing fuse is a sign of an underlying electrical problem. Consult a qualified mechanic to identify the issue and fix it.
Some cars have spare fuses already installed in the fuse box, but it’s always a good idea to check and add more fuses if necessary.
Fuses must be replaced if they blow; they cannot be reset.
Electrical errors, short circuits, overloaded circuits, and defective components are some common reasons.
In order to safeguard the particular electrical components they serve, various circuits may contain fuses with variable ratings.
In order to prevent electrical risks, it is often safer to change fuses while the car is not in motion.
To provide adequate safety and harmony with the electrical system of your Fiat 500L, it is ideal to use fuses that have been approved by the vehicle’s manufacturer (OEM fuses).
