2005 CHEVROLET CLASSIC ECU

Fuses and Circuit Breakers
The wiring circuits in your vehicle are protected from
short circuits by a combination of fuses, circuit breakers
and fusible thermal links in the wiring itself.
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 a 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.
There are three fuse blocks in your vehicle:
two instrument panel fuse blocks and the engine
compartment fuse block.
There is a fuse puller located on the engine
compartment fuse block. It can be used to easily
remove fuses from the fuse block.
Instrument Panel Fuse Block
The instrument panel fuse
blocks are located at each
end of the instrument
panel. To access
the fuses, open the fuse
panel door by pulling out.
To reinstall the door, insert the hooks at the front end
first, then push the door into the instrument panel
to secure it.
