Fuses and fuseboxes
All electrical functions and components are protected by a number of fuses in order to protect the vehicle’s electrical system from damage by short-circuiting or overloading.
WARNING
Never use a foreign object or a fuse with a higher amperage than that specified to replace a fuse. This could cause significant damage to the electrical system and possibly lead to a fire.
If any electrical component or function is not responding, the component may have blown a fuse due to temporary overload. If the same fuse blows repeatedly, there may be a problem with the component. Volvo recommends contacting an authorized Volvo workshop to have the components checked.
Location of fuseboxes
The illustration is generic – appearance may vary according to vehicle model.
- Engine compartment
- Under the glove compartment
- Trunk/cargo compartment
Replacing fuses
All electrical functions and components are protected by a number of fuses in order to protect the vehicle’s electrical system from damage by short-circuiting or overloading.
-
Refer to the fuse diagram to locate the fuse.
-
Pull out the fuse and examine it from the side to determine if the curved metal wire in the fuse is intact.
-
If the wire is broken, replace the fuse with a new fuse of the same colour and amperage.
WARNING
Never use a foreign object or a fuse with a higher amperage than that specified to replace a fuse. This could cause significant damage to the electrical system and possibly lead to a fire. Contact an authorized Volvo workshop for assistance replacing fuses not listed in the Owner’s Manual. If fuse replacement is performed incorrectly, significant damage can be caused to the electrical system.
Fuses in the engine compartment
The fuses in the engine compartment help protect electrical components such as engine and brake functions.
Fuse pliers are provided on the inside of the fuse box cover to assist in removing and inserting fuses. There are also spaces for several extra fuses in the fusebox.
Positions
There is a decal with a diagram of the locations of the fuses on the inside of the cover.

FAQs
Fuses in a home’s electrical system protect against electrical overloads and short circuits by interrupting the circuit, preventing potential damage or fires.
Fuse boxes are often located in utility rooms, basements, garages, or other accessible areas of a home.
A blown fuse often has a visibly broken or melted filament. In some cases, it may be discolored or charred.
To fix a blown fuse at home, you may need a flashlight, a fuse puller or pliers, and replacement fuses of the same amperage rating.
Yes, circuit breakers serve a similar purpose as fuses and can be used as an alternative for overcurrent protection.
To replace a blown fuse, first, disconnect the power source, then use a fuse puller or pliers to remove the blown fuse and replace it with a new one of the same amperage rating.
The amperage rating on a fuse indicates the maximum amount of current it can handle. It’s crucial to use a fuse with the correct amperage rating to avoid overloading the circuit.
It’s not recommended to use a higher amperage fuse, as it can lead to electrical system damage or fires. Always replace with the same amperage fuse.
Common reasons for blown fuses include overloading circuits, faulty appliances, short circuits, and electrical issues.
After replacing a blown fuse with a new one, you can reset the circuit by turning the corresponding circuit breaker or switch back to the “on” position.
It’s essential to disconnect the power source before fixing a blown fuse to avoid electrical shock or injury.
Fuse box diagrams for homes may not be readily available online, but you can often find them in the home’s documentation or contact an electrician for guidance.
Common signs of electrical issues include flickering lights, frequently tripped circuit breakers or blown fuses, and outlets or switches that feel warm to the touch.
To prevent blown fuses, avoid overloading circuits, use surge protectors for sensitive electronics, and regularly inspect and maintain your electrical system.
If you’re unsure about fixing a blown fuse or if the problem persists, it’s advisable to consult a licensed electrician for professional assistance. Electrical issues can be complex, and safety is paramount when working on your home’s electrical systems.
