GENERAL DESCRIPTION
The exterior lighting system includes the
headlights (and headlight motors to raise or lower the
headlights), front
parkinghurn signal lights, front
cornering lights, fog lights, rear
tail/stop/turn signal
lights, back-up lights, license plate lights, center
high-mounted stoplight, and the underhood light; it
also includes all associated wiring, controls and related
hardware for these lights.
BACK-UP LIGHTS - The back-up lights are
next to the rear license plate. They will come on when
the transmission is shifted to Reverse. On cars with an
automatic transmission, the back-up lights are
activated by the neutral start switch. On cars with a
manual transmission, they are activated by a separate
back-up light switch on the transmission. For more
information, see Section 7.
CENTER HIGH-MOUNTED STOPLIGHT-
The center high-mounted stoplight, in the center of the
rear spoiler, will come on whenever the brake pedal is
pushed down. The light is powered separately from the rear
tail/stop/turn signal
lights through a separate
circuit in the stoplight switch (see Section
8A).
EXTERIOR LIGHT MONITOR - The Driver
Information Center, on cars so equipped, also monitors
certain front and rear lights. When a bulb burns out,
the message
"FRONT LAMP" or "REAR LAMP"
will appear in the DIC display, and a light will come
on to indicate which bulb has burned out. For more
information, see Section
8A.
FOG LIGHTS -The fog light switches are to the
left of the steering column on the edge of the
instrument panel. To use the fog lights, first turn on the
headlights or parking lights. Then, push the middle
switch (with the fog light symbol) to turn on the fog
lights. Push the left
("OFF") switch to turn off the fog
lights.
The fog lights should not be used as a substitute
for the headlights.
Switching to high-beam headlights will turn off
the fog lights; switching back to low-beams will turn
the fog lights on again.

KEY IDENTIFICATION AND USAGE
REPLACEMENT LOCK CYLINDERS
The lock cylinder keyway is designed so that
other model keys will not enter a current model lock
cylinder. Two noninterchangeable keys are used.
CB Square headed key is used in the ignition lock
cylinder.
o Oval headed key is used in all other lock
cylinders.
Key identification is obtained from the four
character key code stamped on the knockout portion
of the key head and an identification letter stamped on
the key shank. After the code number has been
recorded by the owner, the plugs should be knocked
out of the key head. From these numbers, the lock
combination can be determined by use of a code list
(available to owners of key cutting equipment from
equipment suppliers). If key code numbers are not
available from records or from the knockout plug, the
lock combination (tumbler numbers and position) can
be determined by laying key on diagram in Figure
1.

CUTTING KEYS
Lock cylinders are available from service parts
warehouses. The new cylinder has a locking bar staked
in place. Tumblers are also available and must be
assembled into the cylinder.
ASSEMBLING AND CODING LOCK CYLINDERS
All Lock Cylinders Except Rear Stowage
Compartment
Tumblers for all locks are shaped exactly alike
with the exception of the notch position on one side.
As the key is inserted in the lock cylinder, tumblers are
lowered to the correct height so that notches on each
tumbler are at the same level. When the notches on all
six tumblers line up, the side bar is pushed into the
notches by two small springs. This allows the cylinder
to turn in its bore. Five types of tumblers are used to
make the various lock combinations. Each tumbler is
coded according to a number,
1 through 5, stamped on
its side.
Assemble (Figs. 2 and 3)
1. Determine tumbler numbers and arrangement.
a. With numerical
key code, use code list
provided by key cutting equipment supplier.
b. Without numerical
key code or without
code list, refer to Figure
1.
o Lay key on key code diagram. Be sure
key is outlined by diagram.
Determine special code from the code list or the
key code diagram (Fig.
1). 3.
o Cut a blank key to the proper level for each of six
tumbler positions.
4.
Start with position number one. Find
and record lowest level (tumbler
number) that is visible. Repeat for
each of the remaining five positions.
Starting with position one [open end or head of
cylinder), insert tumblers in their proper slots in
the order called for by the code (Fig.
2).
Pull side bar out with fingers so that tumblers will
drop completely into place.
Insert one tumbler spring above each tumbler.

LUBRICATION
Mechanical parts having contacting surfaces in
relative motion with other body parts are lubricated
during assembly. To maintain ease of operation, it is
recommended that these parts be lubricated at the
basic service intervals shown in the Maintenance
Schedule with the following lubricants:
Rear Stowage Compartment Lock Cylinder Door hinges - oil (30 weight preferred). Apply
A lock cylinder with snap-in tumblers is used for lubricant
to roller and hinge pin bushings.

surfaces as this could cause improper
positions are standard tumbler positions depending roller operation.

1 H-14 GENERAL INFORMATION - F STYLE
NOTICE: Service part must be primed with a
coating of special polypropylene primer according
to factory recommendations. Failure to use the
required primer as directed will result in color coat
lifting and/or peeling problems. Use
Polypropylene Primer, part no. 1052364, or
equivalent.
1. Wash part with a solvent such as Acryli-Clean,
Pre-Kleano, Prep-Sol or equivalent. Follow label
directions.
2. Apply
a thin, wet coat of polypropylene primer
according to label directions. Wetness of primer
is determined by observing gloss reflection of
spray application in adequate lighting. Be sure
primer application includes all edges. Allow
primer to flash dry one minute minimum and ten
minutes maximum.
3. During the above flash time period (1 to 10
minutes), apply conventional interior acrylic
lacquer color as required and allow to dry before
installing part. Application of color during above
flash time range promotes best adhesion of color
coats.
PAINTING RIGID OR HARD ABS PLASTIC
PARTS
Rigid or hard ABS plastic requires no primer.
Conventional interior acrylic lacquers adhere
satisfactorily to hard ABS plastics.
1. Wash part with a solvent such as ~cr~li-clean,
Pre-Kleano, Prep-Sol or equivalent.
2. Apply conventional interior acrylic lacquer color
according to trim combination (see paint supplier
color chart for trim and color code). Apply only
enough color for proper hiding to avoid washout
of "grain" effect.
3. Allow to dry following label directions and then
install part.
PAINTING VINYL AND FLEXIBLE (SOFT) ABS
PLASTIC PARTS
The outer cover material of flexible instrument
panel cover assemblies is made mostly of ABS plastic
modified with PVC or vinyl. The same is true of many
padded door trim assemblies. The soft cushion padding
under
ABS covers is urethane foam plastic.
The most widely used flexible vinyls (polyvinyl
chloride) are coated fabrics as used in seat trim, some
door trim assemblies, headlinings and sunshades. Most
head restraints are covered with flexible vinyls.
Examples of hard vinyls are door and front
seatback
assist handles, coat hooks and exterior molding inserts. The
paint system for vinyl and flexible
ABS
plastic involves the use of interior vinyl color and a
clear vinyl top coat, No primer or primer-sealer is
required.
1. Wash part with a vinyl cleaning and preparation
solvent, such as Vinyl Prep, Vinyl Prep
Conditioner or equivalent. Wipe off cleaner while
still wet with clean, lint-free cloth.
2. As soon as the surface has been wiped dry, apply
interior vinyl color in wet coats. Allow flash time
between coats. Follow label directions. Use
proper vinyl color as shown by interior trim code
combination. Apply only enough color for proper
hiding to avoid washout of grain effect.
3. Before color flashes completely, apply one wet
double coat of vinyl clear top coat. Use top coat
with appropriate gloss level to match adjacent
similar components. The clear coat is necessary
to control the gloss requirement and to prevent
crocking (rubbing-off) of the color coat after
drying.
4. Allow to dry according to label directions before
installing part.
AVAILABILITY OF COLORS FOR PAINTING
INTERIOR PLASTIC PARTS
Interior colors are color keyed to trim code
combination numbers located on the body number
plate or service parts identification label.
Conventional interior acrylic lacquer colors are
designed for use only on hard trim parts, such as:
1. Steel parts (primer and/or sealer required on new
service parts)
2. Hard
ABS plastic (no primer necessary)
3. Hard polypropylene plastic (special primer
required)
Each major paint supplier provides an interior
color chart which identifies the stock number, color
name, gloss factor and trim code combination number
for each conventional interior color.
Vinyl interior colors are designed for soft trim
parts such as instrument panel cover assemblies, door
trim assemblies and head restraints. These colors
require a final top coat of clear vinyl. Instrument panel
covers require a nonglare final top coat. Other trim
parts require a degree of gloss to match similar
adjacent parts. Use interior vinyl colors and clear vinyl
finishes such as Ditzler Vinyl Spray Colors, American
Jetway UR-1 Vynicolor or equivalents.
SPECIAL BODY TOOLS
Figure 38 shows the special body tools that are
recommended as aids in servicing the various body
components. Equivalent tools may be substituted.

DOOR JAMB SWITCH
Door jamb switch assemblies consist of a plunger,
plunger collar, threaded retainer and terminals. They
are installed in the front and rear door hinge pillars.
When the door of the vehicle is closed, the plunger is
depressed which creates an open in the ground circuit.
When the door is opened, the plunger is released and
completes the circuit to ground (Fig. 41).
When a new jamb switch is installed and the door
is closed the first time, the plunger is forced into the
sleeve and automatically adjusts the jamb switch for
that particular door. If a jamb switch fails, it should not
be readjusted by hand. A new jamb switch should be
installed.

DOOR HARDWARE LUBRICATION
The mechanical components of the door
assembly are lubricated during assembly. If additional
lubrication is required, use the following lubricants.
Black lock cylinders should be lubricated with a light
oil. All other door lock cylinders should be lubricated
with a general purpose silicone lubricant, part no.
1052277 or equivalent. Door hinge pins and rollers
should be lubricated at normal service intervals with 30
weight engine oil. Do not lubricate hinge roller to
hold-open link contacting surfaces as this may prevent
the roller from rolling properly. The remainder of all
door hardware mechanisms except lock assemblies can
be lubricated with part no. 1052349, Lubriplate
Spray-Lube "A", part no. 1052196, Lubriplate
Auto-Lube "A" or equivalent.
HARDWARE ATTACHMENT THREAD LOCKING
All door hardware production attaching screws
contain an epoxy thread-locking compound to insure
that the minimum original torque setting will be
maintained.
Service attaching screws may not contain a
thread-locking compound. To prevent loosening of
service screws or to renew thread-locking
characteristics of production screws, the threads of the
fastener(s) can be treated with part no. 1052279,
Loctite 75 (or equivalent) which is a two-part material
applied to the hardware attachment as a liquid. Upon
installation and tightening, the adhesive cures to bond
the attachment and prevent loosening or back out. The
adhesive bond does not prevent future attachment
removal if required. Loctite 75 or equivalent can be
used on any threaded fastener.
DOOR LOCK SYSTEM
This portion of the manual contains the service
operations necessary to remove the door lock and lock
cylinder assemblies. Any work performed on lock
system hardware requires the removal of the door trim
panel and inner panel water deflector.
Service procedures for spring clips, connecting
rods, locking rods, inside handles, outside handles and
the door lock striker were described previously in this
section.
DOOR LOCK ASSEMBLIES
A fork bolt lock design is utilized which includes
a safety interlock feature. The door is secured in a
closed position when the door lock fork bolt snaps over
the striker bolt. Doors can be locked from the inside
by sliding the door inside locking knob. Both doors can
be locked from the outside by simply sliding the
interior door locking knob and closing the door or by
using the proper key.
Do not attempt repairs to correct lock
discrepancies. Make corrections through
replacement of lock assembly.
