Downloaded from www.Manualslib.com manuals search engine Fuses and Circuit
Breakers
The wiring circuits in your vehicle are
protected from short circuits by a
combination of maxi-fuses, mini-fuses
and circuit breakers. This greatly reduces
the chance of fires caused by electrical
problems.
There are three fuse centers on your
vehicle. One
is in the right side of your
instrument panel. Turn the knob and pull
the door to access the fuses. The other
two fuse blocks are in the
engine compartment. One is part of the
Forward Lamp wiring harness
(A), and
the other is part of the ECM-Engine
wiring harness
(B).
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 correct
size.
If you ever have a problem on the road
and don’t have a spare fuse, you can
borrow one of the correct value. 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 size you need. Replace it as soon
as you can.
Headlights
The headlight wiring is protected by a
circuit breaker
in the switch. An electrical
overload will cause the lights to go on and
off, or in some cases to remain
off. If this
happens, have your headlight wiring
checked right away.
Windshield Wipers
The windshield wiper motor is protected
by a circuit breaker and a fuse. If the
motor overheats due to heavy snow, etc.,
the wiper will stop until the motor cools.
If the overload is caused by some
electrical problem and not snow, etc.,
be sure to get
it fixed.
Power Windows and Other Power
Options
Circuit breakers 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.

WHAT TO DO
Lubricate the key lock cylinders with the lubricant specified in Section D.
Lubricate all body door hinges. Also lubricate all hinges and latches, including those for the hood,
rear compartment, glove box door, console door and any folding seat hardware. Section
D tells
you what to use.
1. Before you start, be sure you have enough room around the vehicle.
2. Firmly apply both the parking brake (see “Parking Brake” in the Index if necessary) and the
regular brake.
....
NOTE: Do not use the accelerator pedal, and be ready to turn off the engine immediately if it
starts.
3. On automatic transmission vehicles, try to start the engine in each gear. The starter should
work only in
“P” (Park) or “N” (Neutral). If the starter works in any other position, your
vehicle heeds service.
On manual transmission vehicles, put the shift lever in “N” (Neutral), push the clutch down
halfway and try to start the engine. The starter should work only when the clutch is pushed
down all the way to the floor. If the starter works when the clutch isn’t pushed all the way
down, your vehicle needs service.
