(6) Remove the screws attaching lens, dial and
gauge assembly to the housing. The bottom screws
attaching lens to the housing can be accessed without
removing the foam pad.
(7) Remove the lens, dial and gauge assembly from
housing.
(8) Remove the two screws holding the odometer to
dial and gauge assembly. When setting the dial/gauge
and/or cluster assembly down, it must be face up or
the gauge operation will be damaged.
INSTALLATION
For installation, reverse the above procedures.
Carefully place the dial and gauge assembly on the
cluster and ensure that the odometer connector is
placed through the board. Install with a slight rock-
ing motion to ensure the pins on gauges line up.

GENERAL INFORMATION
INTRODUCTION
Operating instructions for the factory installed
audio systems can be found in the Owner's Manual
provided with the vehicle.
The vehicles are equipped with an Interior (Igni-
tion Off Draw) fuse in the Power Distribution Center
located in the engine compartment. After the Interior
(IOD) fuse or battery has been disconnected the clock
will require resetting.
DESCRIPTION AND OPERATION
INTERFERENCE ELIMINATION
The radio utilizes a ground wire plugged on to a
blade terminal and is bolted to the radio chassis.
Both connector and terminal should be securely
attached. The engine has three separate ground
straps to suppress ignition noise which may interfere
with radio reception.
²Left engine mount clip on strap
²Engine to shock tower reinforcement
²Rear strut to body, clip-on strap
Inductive type spark plug cables in the high ten-
sion circuit of the ignition system complete the inter-
ference suppression. Faulty or deteriorated spark
plug wires should be replaced.
In addition, there is a capacitor mounted on the
cylinder head which also helps suppress ignition
noise.
DIAGNOSIS AND TESTING
AUDIO DIAGNOSTIC TEST PROCEDURES
CAUTION: The CD player will only operate between
approximate temperatures of -23ÉC and +65ÉC (-10ÉF
and +145ÉF).
Whenever a radio malfunction occurs;
(1) First check FUSES:
(a) Power Distribution Center (PDC), Interior
lamp fuse, M1 - Radio Memory Feed
(b) Fuse Block:
(I) Fuse 12, Illumination in the fuse block
(II) Fuse 16, Ignition feed in the fuse block
NOTE: The vehicles are shipped with the INTERIOR
LAMP fuse disconnected.
(2) Verify, the radio wire harness are properly con-
nected before starting normal diagnosis and repair
procedures. Refer to Audio Diagnosis table and/or
Group 8W, Wiring Diagrams, Radio Section.

DIAGNOSIS AND TESTING (Continued)

ANTENNA
The antenna has a short cable which connects into
the instrument panel harness. The connection is
made on the right side of the instrument panel.
Antenna performance may be tested by substitut-
ing a known good antenna. It is also possible to
check short or open circuits with an ohmmeter or
continuity light once the antenna cable is discon-
nected from the radio as follows:
(1) Continuity should be present between the
antenna mast and radio end pin of antenna cable
plug (Fig. 1).
(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 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
ANTENNA
REMOVAL
(1) Remove antenna mast by unscrewing mast
from antenna body (Fig. 3).
(2) Locate the antenna lead disconnect in the
instrument panel wire harness above the right kick
panel. Disconnect the antenna cable from cable lead.
(3) Unfasten push pins from the rear of the plastic
inner fender shield and move shield to gain access to
mounting screws (Fig. 4).
(4) Remove mounting screw and remove antenna
base and cable assembly from under the fender.
INSTALLATION
(1) Align antenna adapter tongue with grove in
the fender hole and push adapter into fender.
(2) From under the fender, push the antenna base
and cable assembly through the adapter in the
fender. Tighten mounting screw to 7 N´m (75 in. lbs.).
(3) Seat the grommet in the side panel and con-
nect the cable to the instrument panel harness con-
nector.
(4) Install the plastic inner fender shield.
(5) Connect the antenna cable to the cable lead.
