2004 BUICK RAINIER engine

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 res
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.
If you ever have a problem on the road and don’t have
a spare fuse, you can borrow one that has the same
amperage. Just pick some feature of your vehicle
that you can get along without — like the radio or
cigarette lighter — and use its fuse, if it is the correct
amperage. Replace it as soon as you can.
Engine Compartment Fuse Block
The fuse block is located under the hood in the
engine compartment on the driver’s side of the vehicle.
SeeEngine Compartment Overview on page 5-14
for more information on location.
Remove the primary cover by pressing the two locking
tabs. Remove the secondary cover by snapping off
while lifting. To reinstall the fuse panel cover, reverse
the sequence.
