Electrical System
Add-On Electrical Equipment
Notice: Do not add anything electrical to your
vehicle unless you check with your dealer
first. Some electrical equipment can damage
your vehicle and the damage would not
be covered by your warranty. Some add-on
electrical equipment can keep other
components from working as they should.
Add-on equipment can drain your vehicle’s battery,
even if your vehicle is not operating.
Your vehicle has an airbag system. Before
attempting to add anything electrical to your
vehicle, see Servicing Your Airbag-Equipped
Vehicle on page 86.
Power Windows and Other Power
Options
Circuit breakers in the rear fuse block protect the
power windows and other power accessories.
When the current load is too heavy, the circuit
breaker opens and closes, protecting the circuit
until the problem is fixed or goes away.
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 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.
You will find a fuse puller clipped in both of the
fuse blocks. Snap the wide end of the fuse puller
at the side indentations and pull the fuse out.
The MaxiFuses are located in two fuse blocks,
one located in the engine compartment on
the passenger’s side and the other under the rear
seat on the driver’s side. If a MaxiFuse should
blow, have your vehicle serviced by your dealer
immediately.
Underhood Fuse Block
The underhood fuse block is located on the
passenger’s side of the engine compartment.
Remove the fuse cover and secondary service
cover to access the fuse block.
