Replacing fuses
There are relay/fuse boxes located in the
engine compartment and the passenger com-
partment.
If an electrical component fails to function, this
may be due to a blown fuse. The easiest way
to see if a fuse is blown is to remove it.
To do so:
1. Pull the fuse straight out. If a fuse is difficult
to remove, special fuse removal tools are
located on the inside of the fuse box cov-
ers.
2. From the side, examine the curved metal
wire in the fuse to see if it is intact.
3. If the wire is broken, insert a new fuse of
the same color and amperage (written on
the fuse).
If fuses burn out repeatedly, have the electrical
system inspected by a trained and qualified
Volvo service technician.
WARNING
Never use metal objects or fuses with higher
amperage than those stated on the follow-
ing pages. Doing so could seriously damage
or overload the vehicle's electrical system.

Questions and answers
When i open the door on my 2010 S40 the lights do not flash. Please can you tell me why!
The issue may be caused by an electrical fault, likely related to a bad ground or faulty wiring. In similar cases, problems with the Central Electronic Module (CEM) or its connectors can cause unusual behavior with interior lights and the dashboard. It’s possible the car is misinterpreting the door open signal or the interior light circuit is interfering with other systems. Checking and reseating the CEM connectors and inspecting grounding points may help identify the cause.
