Volvo EX40 (2025 – 2027) Fuse Box Location & Diagrams
The Volvo EX40 (2025–2027) features multiple fuse boxes that protect its electrical circuits and vehicle systems. Knowing their locations and fuse assignments helps identify electrical faults, replace blown fuses, and maintain essential components such as lighting, power windows, climate control, and infotainment systems.
Fuse Box Location
Passenger Compartment Fuse Box
To access the fuse box you need to pull back the floor mat underneath the glove box.
Engine Compartment Fuse Box
To access the fuses you need to unclip the box lid.
Removing panels under the bonnet
The panels overlap one another so you need to remove and install them in a certain order.
- Panel A Provides access to the negative battery terminal for jump starting your car.
- Panel B
- Panel C
- Panel D Provides access to the positive battery terminal for jump starting your car and to fuses under the bonnet.
- Panel E
- Panel F Cover for storage compartment under the bonnet.
- Washer fluid reservoir cap.
The panels are held in place with plugs. To remove these plugs, use a screwdriver or similar tool to press in the locking pin in the middle of the plug. When the pin is pressed in far enough, you can pull the plug out. Avoid pushing the pin all the way through the plug, as this could cause it to dislodge and fall down between components.
