/njector 3365 Fuse
(3800 V6 ENGINE ONLY)
This 20-amp fuse is located underhood,
on a bracket just behind the passenger
side headlight.
It is mounted on the face
of the bracket in the position closest to
the passenger side of the vehicle. The
fuse services the injectors, fuel pump,
oil pressure sender and fuel pump
switch.
To access the fuse, pry back the latch
with a screwdriver,
then pull down on
the base of the unit. If you need to
replace the fuse, be sure to use a
20-amp fuse.
Push the base of the unit
firmly up into
the cover until
the latch snaps into the
locked position.
Head/ight Wiring
The headlight wiring is protected by a
circuit breaker in the light 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 system 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, have it fixed.
Power Windows and Other
Power Options
Circuit breakers in the circuit
breakerhelay panel 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.
