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
- Engine compartment
- Under the left front seat
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 color and amperage.

FAQs
A fuse is a protective device in a car’s electrical system that is designed to break the circuit and prevent electrical damage in case of an overload or short circuit.
The fuse box in the 2020 Volvo XC40 is typically located in the engine compartment or the interior of the vehicle.
To access the fuse box in the Volvo XC40, consult your owner’s manual for the exact location and removal procedure. It may involve removing a cover or panel.
A blown fuse can often be visually identified by a broken filament inside the fuse or a discolored appearance. You can also use a multimeter to check for continuity.
You’ll typically need a fuse puller or a pair of needle-nose pliers to remove fuses. It’s also a good idea to keep spare fuses of various amperages on hand.
No, it’s important to use the correct type and amperage of fuse as specified in your owner’s manual. Using the wrong fuse can cause electrical problems or even damage.
Your owner’s manual will have a fuse diagram or chart that shows which fuse controls each electrical component in your car. You can use this to identify the faulty fuse.
Blown fuses can be caused by various factors, including electrical faults, short circuits, overloading the circuit, or faulty components.
No, you should never replace a fuse with one of a higher amperage rating. This can lead to electrical damage or even fire hazards.
If a fuse keeps blowing, it may indicate an underlying electrical issue. Consult a qualified mechanic to diagnose and fix the problem.
Some fuses may be related to critical safety systems or advanced electronics. In such cases, it’s best to have a professional technician handle the replacement.
