2004 PONTIAC BONNEVILLE Owners Manual

Fuses and Circuit Breakers
The wiring circuits in your vehicle are protected from
short circuits by a combination of fuses and circuit
breakers. This greatly reduces the chance of damage
caused by electrical problems.
Look at the silver-colored band inside the fuse. If the
band is broken or melted, replace the fuse. Be sure you
replace a bad fuse with a new one of the identical
size and rating.
The MaxiFuses are located in two fuse blocks, one in
the engine compartment and the other under the
rear seat. If a MaxiFuse should blow, have your vehicle
serviced by your dealer immediately.
Removing Fuses
You will nd a fuse puller attached in both of the fuse
blocks. Snap the wide end of the fuse puller on to
the fuse at the side indentations, then hold the puller
and pull the fuse out.
Engine Compartment Fuse Block
The engine compartment
fuse block is located in the
front of the engine
compartment on the
passenger’s side of the
vehicle. SeeEngine
Compartment Overview on
page 5-14for more
information on location. Lift
the cover to gain access.
Fuse 22 or 23 can be moved to the outer position to
enable the accessory power outlet or cigarette lighter
when the ignition is not on. See your dealer for
additional assistance, if needed.
