Replacing fuses
If an electrical component fails to function, it is likely that a fuse has blown due to a temporary circuit overload.
The fuse boxes are located in three different places:
A - Relays/fuse box in the engine compartment *
B - Fuse box in the passenger compartment
C - Relays/fuse box in the trunk *
A label on the inside of each cover indicates the amperage and the electrical components that are connected to each
fuse.
The easiest way to see if a fuse is blown is to remove it. Pull the fuse straight out. If a fuse is difficult to remove, you
will find a special fuse removal tool in the passenger compartment fuse box. From the side, examine the curved metal
wire to see if it is broken. If so, put in a new
fuse of the same color and amperage (written on the fuse). Spare fuses are stored in the fuse box in the passenger
compartment. If fuses burn out repeatedly, have the electrical system inspected by an authorized Volvo retailer.
* The relays and main fuses in the engine compartment and trunk should only be replaced by an authorized
Volvo retailer. You can, however, replace the ordinary fuses if necessary.
pg.89 Fuses in the engine compartment
Relays/fuses in the engine compartment
The relay/fuse box in the engine compartment contains 8 main fuses and space for 21 ordinary fuses. The main fuses
should only be replaced by an authorized Volvo retailer. You can, however, replace the ordinary fuses if necessary.
Be sure to replace a blown fuse with a new one of the same color and amperage (written on the fuse).
