Volvo V90 Fuse Box Locations and Diagrams (2016-2025)

The luxury station wagon Volvo V90, introduced in 2016, offers a blend of refined Scandinavian design, spacious practicality, and advanced safety and infotainment technologies. Built on Volvo’s SPA (Scalable Product Architecture) platform, it is available with a range of efficient powertrains, including mild-hybrid, Twin Engine plug-in hybrid, and Recharge PHEV variants. Production continues through 2025.

In this article, you will find fuse box diagrams for the Volvo V90, covering model years 2016, 2017, 2018, 2019, 2020, 2021, 2022, 2023, 2024 and 2025. These diagrams help identify the correct fuses and relays used to protect essential electrical components and systems.

What’s Included:

Fuse Box Diagrams – Visual references showing fuse and relay layouts by model year and configuration.
Fuse Panel Locations – Guidance on locating each fuse panel (e.g., passenger compartment, cargo area, engine bay).
Fuse Assignments – Comprehensive tables showing what each fuse and relay controls, making diagnosis and replacement easier.

Whether you’re troubleshooting an electrical problem or installing accessories, this guide will help you maintain and service your Volvo V90 (2016–2025) with confidence.
