6-64 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.
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 or use one of the spare fuses in the underhood
fuse and relay center. 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 right
amperage. Replace it as soon as you can.
There are two fuse blocks in your vehicle: the floor
console fuse block and the underhood fuse and
relay center.Floor Console Fuse Block
The floor console fuse block is located to the left of the
glove box near the floor.
The fuses marked spare are available if a replacement
fuse is needed.
Pull the door open to access the fuse block.
