Fuses and Circuit Breakers
The wiring circuits in the vehicle are protected from
short circuits by a combination of J-Case fuses,
mini-fuses and circuit breakers. This greatly reduces
the chance of fires 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 do not
have a spare fuse, you can borrow one that has
the same amperage. Just pick some feature of the
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. Vehicles with the ZR–1 package have an intercooler
relay located on the fan shroud. See your dealer/
retailer.
Vehicles with the ZR–1 package also have a fuel
system mini-fuse. It is located near the battery in the
battery storage compartment in the rear of the vehicle.
Instrument Panel Fuse Block
The instrument panel fuse block is located on the
passenger side of the vehicle, under the instrument
panel and under the toe-board.
Remove the carpet and toe-board covering to access
the fuse block by pulling at the top of each corner of the
panel. Open the fuse block cover to access the fuses.
You can remove fuses using the fuse puller.
