2020 Volvo V90 Fuses and Fuse Box | How To Check And Fix
Fuses and fuseboxes
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 possi-bly lead to a fire.
The illustration is generic – appearance may vary according to vehicle model.
- Engine compartment
- Under the glove compartment
- Trunk/cargo compartment
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 amper-age.
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 possi-bly 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 loca-tions of the fuses on the inside of the cover.

FAQs
Fuses in a vehicle protect electrical components from damage due to overloads or electrical faults by breaking the circuit when such conditions occur.
The location of the fuse box may vary, but it is typically found in the engine compartment or in the interior of the vehicle, often under the dashboard or in the glove compartment.
A blown fuse can often be identified by a visible break in the wire inside the fuse. You can also use a multimeter to test the continuity of the fuse.
You may need a fuse puller or a pair of needle-nose pliers to remove the blown fuse and a spare fuse of the same amperage rating to replace it.
The amperage rating is typically printed on the top of the fuse or listed in the vehicle’s owner’s manual.
Fuses protect various electrical components, including headlights, taillights, radio, power windows, air conditioning, and more.
It is not recommended to replace a fuse with one of a different amperage rating, as it may not provide the proper protection or could lead to electrical problems.
Refer to the vehicle’s owner’s manual for instructions on how to access the fuse box in your specific model.
Yes, the fuse box cover often includes a diagram or legend that indicates the function of each fuse and its amperage rating.
Check the fuse box for any blown fuses by visually inspecting them or using a multimeter. If you find a blown fuse, replace it with one of the same amperage rating.
It’s important to disconnect the vehicle’s battery before working with fuses to prevent electrical shock or damage to the vehicle’s electrical system.
Prevent blown fuses by avoiding overloading electrical circuits, using the correct amperage-rated fuses, and addressing electrical issues promptly.
Replacing fuses is a relatively simple task that can often be done by vehicle owners. However, if you are unsure or uncomfortable doing it yourself, it’s best to consult a professional mechanic.
If replacing a fuse does not resolve the issue, there may be a deeper electrical problem that requires professional diagnosis and repair.
Airbags typically have their own dedicated power source and may not be protected by fuses in the same way other electrical components are.
