2007 GMC ENVOY DENALI radio

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 390for 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.
