Fuse box diagram (fuse layout), location, and assignment of fuses and relays Volvo 850, 850R and 850TR (1993, 1994, 1995, 1996, 1997).
Checking and Replacing Fuses
The fuses help protect the vehicle’s electrical components from overloading. 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:
- Switch off the headlights, the ignition, and all electrical consumers.
- Open the appropriate fuse box.
- See diagrams below for details about which fuse to check.
- Pull the fuse straight out.
- From the side, examine the curved metal wire in the fuse to see if it is intact. If the wire is broken, insert a new fuse of the same color and amperage (written on the fuse).
- Replace the cover.
If fuses burn out repeatedly, have the electrical system inspected by a trained and qualified Volvo service technician.
Notice
- Never use metal objects or fuses with a higher amperage than those stated on the following pages. Doing so could seriously damage or overload the vehicle’s electrical system.
- Never repair fuses.
