GENERAL DESCRIPTION
INSTRUMENT PANEL AND GAGES
INSTRUMENTS
Instruments consist of fuel gage, temperature
The instrument panel on most cars is a sing,e unit indicator light, generator light, oil pressure indicator
design and all parts attach to the main instrument light, and speedometer. See Section 9F for optional
panel with clips and screws. To service the instrument Gages and tachometer. Service on instruments
panel and components see on-car service information, can be obtained through authorized repair stations.
However, knowledge of instrument circuit checks will
PRINTED CIRCUIT
All models are equipped with printed circuits
which supply current to most instrument panel lights
and instruments. These circuits are made of copper foil
which is die cut and bonded to a polyester base film
(usually mylar). The printed circuit electrical power is
supplied by a connector containing several wires, as
shown in the instrument panel wiring harness
installation instructions. The connector also helps
retain the printed circuit to the speedo cluster. The rest
of the circuit is retained by additional connectors (if
used) and snap-in
bulbs/sockets. For individual
printed circuit diagrams, see Section
8A-80/8 1/82/83,
'Instrument Panel'. help
in determining if operating difficulties lie in the
instrument itself or its related circuit.
Instruments have been designed for easy removal
by elimination of separate wiring. With the wiring
provisions integrated with the instrument panel wiring,
the instruments can be removed after removing the
trim and lens.
SPEED SENSORS
There are three speed sensors currently in use:
1. PINION GEAR; used in mechanical systems
2. PHOTO SPEED SENSORS; used in mechanical
systems
3. PM GENERATOR; used in electronic systems

GENERAL DESCRIPIIOM
ELECTRONIC GLARE CONTROL MIRROR
Service procedures regarding this mirror are
found in the Body Section of this manual.
Fig. 601 EGC Mirror
The EGC mirror has light sensors which monitor
activity in front and back of the mirror and compensate
for brightly lit or extremely dark driving conditions.
After glare is no longer detected in the night mode, a
short time delay is automatically activated, preventing
unnecessary changing as traffic moves in and out
behind the car.
As an added feature, the Automatic
Day/Night
Mirror will hold in the normal viewing mode whenever
the shift selector is placed in reverse. This assures you
of a bright, clear view while backing up.
The Automatic Mirror with EGC (Electornic
Glare Control) is a technological breakthrough using
advanced computer circuitry. It is powered by the
vehicle electrical system and requires no batteries or
scheduled maintenance. Power is drawn only when the
ignition is on.
Illuminated Distance Dial provides a full
range of adjustments to match your eye sensitivity.
Night Mode Indicator illuminates green when
mirror switches to the non-glare position.
Light Sensors monitor ambient lighting
conditions and
headlamp glare, then adjust the mirror
accordingly.
Auto-Off Switch allows fully automatic
operation or manual selection.

FORMED HEADLINING 1. Load the headlining through the rear
The one-piece formed headlining (Fig. 1) consists
of a molded fiberglass substrate covered with a foam
and cloth facing. The one-piece construction requires
the headlining be serviced as a complete assembly.
The headlining is held partially in place by
retaining fasteners located in the headlining which fit
into slots in the roof panel. Final attachment is
accomplished when the interior moldings and
attaching screws that retain the sunshade brackets,
dome lamp base and coat hooks are installed.
Removal
1. Remove the following items:
e Back body opening upper garnish molding
r Windshield side upper garnish molding (1,
Fig. 3 or
6)
e Rear vertical garnish molding
a Windshield header courtesy reading and
console lamp
e Sunshades
e Partially remove shoulder belt bezel and
belt
a Coat hooks and rail panel inserts
2. Grasp headlining assembly with both hands at
outer edges and move to the right of centerline to
disengage fastener assemblies from front
attaching slots.
3. Remove headlining assembly through right front
door.
lnstallation
Care must be exercised when loading assembly.
Excessive flexing may result in damage. compartment
opening.
2. Align headlining with cutouts for sunshades and
