WIPER BLADES
REMOVAL
(1) Lift the wiper arm away from the glass.
(2) Disengage the release tab holding the wiper
blade to the wiper arm and remove the wiper blade
from the wiper arm (Fig. 5) and (Fig. 6).
CLEANING
Wiper blades exposed to the weather for a long
period of time tend to lose their wiping effectiveness.
Periodic cleaning of the wiper blade is recommended
to remove the accumulation of salt and road grime.
The wiper blades, arms and windshield should be
cleaned with a sponge or cloth and a mild detergent
or nonabrasive cleaner. If the wiper blades continue
to streak or smear, they should be replaced. The
wiper blade should run smoothly across the wind-
shield in both directions. The wiper blade should
slightly roll over center when the blade reverses
direction. A wiper blade insert that has lost flexibility
or a wiper arm that has lost spring tension, will
cause the blade to skip or chatter across the wind-
shield. If the wiper blades are new and the wiper
arm spring tension is OK and a chattering sound is
emitted from the wiper(s), the wiper blade is not roll-
ing over center. If this condition exists, (refer to 8 -
ELECTRICAL/WIPERS/WASHERS/WIPER ARMS -
ADJUSTMENTS).
INSTALLATION
(1) Position the blade onto the arm.
(2) Engage the blade to the retainer by pulling up
on the blade until the tabs snap into position (Fig. 5).
WIPER LINKAGE
REMOVAL
(1) Remove the front windshield wiper unit from
vehicle (Refer to 8 - ELECTRICAL/WIPERS/WASH-
ERS/WIPER MODULE - REMOVAL).
(2) Place the wiper unit on a suitable work sur-
face.
(3) Remove nuts holding the cowl cover brackets to
the wiper unit.
(4) Remove cowl cover brackets from the wiper
unit.
(5) Remove nuts holding linkage to the wiper unit.
(6) Remove the wiper linkage from the wiper unit.

IOD FUSE
DESCRIPTION
All vehicles are equipped with an Ignition-Off
Draw (IOD) fuse that is removed from its normal
cavity in the Integrated Power Module (IPM) when
the vehicle is shipped from the factory. Dealer per-
sonnel are to remove the IOD fuse from the storage
location and install it into the IPM fuse cavity
marked IOD as part of the preparation procedures
performed just prior to new vehicle delivery.
The IOD fuse is a 20 ampere blade-type mini fuse
and, when removed, it is stored in a fuse cavity adja-
cent to the washer fuse within the IPM.
OPERATION
The term ignition-off draw (IOD) identifies a nor-
mal condition where power is being drained from the
battery with the ignition switch in the Off position.
The IOD fuse feeds the memory and sleep mode func-
tions for some of the electronic modules in the vehicle
as well as various other accessories that require bat-
tery current when the ignition switch is in the Off
position, including the clock. The only reason the
IOD fuse is removed is to reduce the normal IOD of
the vehicle electrical system during new vehicle
transportation and pre-delivery storage to reduce
battery depletion, while still allowing vehicle opera-
tion so that the vehicle can be loaded, unloaded and
moved as needed by both vehicle transportation com-
pany and dealer personnel.
The IOD fuse is removed from the Integrated
Power Module (IPM) fuse cavity when the vehicle is
shipped from the assembly plant. Dealer personnel
must install the IOD fuse when the vehicle is being
prepared for delivery in order to restore full electrical
system operation. Once the vehicle is prepared for
delivery, the IOD function of this fuse becomes trans-
parent and the fuse that has been assigned the IOD
designation becomes only another Fused B(+) circuit
fuse. The IOD fuse serves no useful purpose to the
dealer technician in the service or diagnosis of any
vehicle system or condition, other than the same pur-
pose as that of any other standard circuit protection
device.
The IOD fuse can be used by the vehicle owner as
a convenient means of reducing battery depletion
when a vehicle is to be stored for periods not to
exceed approximately thirty days. However, it mustbe remembered that removing the IOD fuse will not
eliminate IOD, but only reduce this normal condition.
If a vehicle will be stored for more than thirty days,
the battery negative cable should be disconnected to
eliminate normal IOD; and, the battery should be
tested and recharged at regular intervals during the
vehicle storage period to prevent the battery from
becoming discharged or damaged.
POWER OUTLET
DESCRIPTION
Two power outlets are installed in the instrument
panel center lower bezel. Two additional power out-
lets are incorporated into the left rear C-pillar and
the center console (if equipped). The power outlets
bases are secured by a snap fit. A hinged plug flips
closed to conceal and protect the power outlet base
when not in use.
OPERATION
The power outlet base or receptacle shell is con-
nected to ground, and an insulated contact in the
bottom of the shell is connected to battery current.
The power outlet on the instrument panel marked
with a battery receives battery voltage from a fuse in
the Integrated Power Module (IPM) at all times. The
other power outlet on the instrument panel marked
with a key receives battery voltage only when the
key is in the on position.
The power outlet located in the center console
receives battery voltage all the time when positioned
between thefront seatsand key-on voltage when
positioned between therear seats. The power outlet
located on the C-pillar receives battery voltage only
when the key is in the ON position.
