(3) Continuity should be observed between the
ground shell of the connector and the mounting hard-
ware on the vehicle antenna. The wheel well splash
shield must be removed for access to the antenna
that is mounted on load beam.
BENCH TEST FOR ANTENNA MALFUNCTION
It is also possible to check short or open circuits
with an ohmmeter or continuity light once the
antenna has been removed from the vehicle.
(1) Continuity should be present between the tip of
the mast and radio lead in (Fig. 2).
(2) No continuity should be observed or a very
high resistance of several megohms between the
ground shell of the connector and radio end pin.
(3) Continuity should be observed between the
ground shell of the connector and the mounting
bracket.Wiggle cable over its entire length to
reveal intermittent short or open circuits dur-
ing step 1, 2 and 3.
REMOVAL AND INSTALLATION
CD CHANGER
REMOVAL
(1) Disconnect and isolate the battery negative
cable (Fig. 3).
(2) Using a trim stick (special tool #C-4755), gently
pry out on CD changer bezel and remove.

WINDSHIELD WIPER MODULE
REMOVAL
(1) Disconnect and isolate the battery negative
cable (Fig. 7).
(2) Remove wiper arms and blades. Refer to Wind-
shield Wiper Arm Removal and Installation in this
section.
(3) Remove the left side cowl cover. Refer to Group
23 Body, Cowl Cover Removal and Installation.
(4) Disconnect motor posi-lock harness connector.
(5) Remove windshield wiper module mounting
screws and remove module from vehicle.
INSTALLATION
For installation, reverse the above procedures.
Tighten the mounting screws to 7 to 9 N´m (60 to 80
in. lbs.) torque.
WINDSHIELD WIPER MOTOR
REMOVAL
(1) Remove windshield wiper module. Refer to
Windshield Wiper Module Removal and Installation
in this section.(2) Remove linkage from motor crank. Insert
screwdriver or equivalent between crank and linkage
then twist and lift straight up on linkage.
(3) Remove three motor mounting screws and sep-
arate motor from linkage.
INSTALLATION
For installation add unilube grease to socket and
reverse the above procedures. Tighten the motor
mounting screws to 5 to 6 N´m (45 to 55 in. lbs.)
torque. Tighten drive link nut to 11 to 12 N´m (98 to
106 in. lbs.) torque.
WINDSHIELD WIPER/WASHER SWITCH
To service the wiper switch, refer to Group 8J Turn
Signal and Hazard Warning Systems, Multi-Function
Switch Removal and Installation.
CLEANING AND INSPECTION
WINDSHIELD WIPER BLADE(S)
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
Adjustments, Wiper Arm Adjustment in this section.
ADJUSTMENTS
WINDSHIELD WIPER ARM(S)
(1) Cycle the wiper motor into the PARK position.
(2) Lift the wiper blade off the windshield and
release it.
(3) The wiper blade heel should be parked within 5
mm of the park line. The park line is mark on the
windshield (Fig. 9).
(4) In the event that the wiper blade tip exces-
sively strikes the cowl screen due to long term nor-
mal wear, reposition the wiper blade heel slightly
above the park line. Make sure that the wipers are
in the PARK position.
