STEER NG WHEELS AND COLUMNS
NOTICE: All steering wheel and column fasteners are important attaching parts in that they could affect
the performance of vital parts and systems, and/or could result in major repair expense. They
must be replaced
with one of the same part number or with an equivalent part if
replacement becomes necessary. Do not use a
replacement part of lesser quality or substitute design. 'Torque values must be used as specified during reassembly
to assure proper retention of all parts. There is to be no welding as
it may result in extensive damage and weakening
of the metal.
For prevailing torque
nut(s) and bolts(s), refer to the "Reuse of Prevailing Torque Nut(<) and Bolt(s) " chart
in Section OA.

GENERAL DESCRIPTION
STEERING COLUMN
The function locking energy absorbing steering
column includes three important features in addition
to the steering function:
1. 'The column is energy absorbing, designed to
compress in a front-end collision to minimize the
possibility of an injury to the driver of the car.
2. The ignition switch and lock are mounted
conveniently on this column.
3. With the column mounted lock, the ignition and
steering operations can be locked to inhibit theft
of the car.
The turn signal lever provides for control of
headlight beams, windshield washer and wipers.
The column may be easily

WIPERIWASHER: PULSE, CB4
(Continued from previous page)
CIRCUIT OPERATION
In addition to the features of a conventional
(Non-pulse) wiper system (MIST, LO and HI
speed), the pulse-type windshield
wiperlwasher
system includes an operating mode in which the
wipers make single strokes with an adjustable
time interval between strokes. The time inter-
val is controlled by a Solid State Pulse Timer
Relay in the WiperIWasher Assembly. The
duration of the delay interval is determined by
the Delay Rheostat
in the WiperIWasher Con-
trol Switch.
Pulse Operation
With the WiperlWasher Switch in Pulse,
battery voltage is applied to the WiperlWasher
Motor Module at terminal
B through the GRY
wire. Voltage is also applied to
terminal F
through the PNK wire and the pulse delay
resistance in the WiperlWasher Switch. The
battery voltage at terminal
B energizes the
Park Relay which closes its contacts. In
response to the voltage at terminal F, the Solid
State Timer momentarily closes contact
A on
the control board which applies the battery
voltage at terminal
B to the contacts of the
Park Relay, starting the Wiper Motor.
A second mechanical arm (end of sweep
input) operates contacts on the Control Board
which cause the contacts at A to open when the
wipers have completed their sweep. Since the Park
Relay remains energized, the wipers do
not park but remain just above the parked posi-
tion until the Control Board closes the contacts
at A again to start
another sweep.
The length of delay time between sweeps is
controlled by the variable Pulse Delay resistor.
The delay is adjustable from zero to
25 seconds.
Low Speed
In the LO position of the WiperIWasher
Switch, battery voltage is applied at terminal C
of the Wiper Motor Module as well as terminal
B, through the DK GRN and GRY wires. The
Park Relay is again energized and battery
voltage is applied to the Park Relay contacts
from terminal
G and the Wiper Motor which
runs continuously.
High Speed
With the Wiper Switch in the HI position,
battery voltage is supplied directly to the
Wiper Motor, without passing through the
Park Relay contacts. The input (PPL wire) is
connected to a separate armature brush for
high speed operation.
When turned off from HI, the wipers com-
plete the last sweep at low speed and park. To
do this, the Wiper Motor receives battery volt-
age
in the OFF position of the Wiper Switch
which is applied through the
DM GRN wire to
terminal C of
61. The Park relay is deenergized
when the WiperlWasher Switch
is moved to
OFF, but the contacts remain closed until the
wipers reach the parked position. The
Wiper Motor is protected by a Circuit
Breaker. If the wipers are obstructed, by snow
or ice for example, the circuit breaker
will open
the circuit. The Circuit Breaker resets automat-
ically when
it cools.
Washer
When the Washer Switch is held ON, battery
voltage is applied to the Control Board through
the PNK and GRY wires. The Park Relay is
energized by the battery voltage at ter
The Control Board turns on the Washer and
Wiper Motors by closing contacts A and
B. The
Control Board turns the Wiper Motor OFF
approximately
6 seconds after it interrupts
power to the Washer Motor. If the Wipers had
been in Pulse, LO, or HI, they would return to
that operation after the wash cycle.
Mist
When the control is moved to MIST and
released, the wipers make one sweep at low
speed and return to park. The circuit operation
is the same as that of LO.

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.

GENERAL DESCRIPTION
Figs. hand 2
The Permanent Magnet (PM) Depressed Park
windshield
(w/s) wiper with remote washer pump sys-
tem consists of a depressed park wiper motor and a
remote washer pump mounted on the washer fluid
container.
Based on the type of control switch used and
whether an optional electronic printed circuit board is
attached in the wiper cover, the system can serve as
either a pulse type wiper-washer system or a standard
type windshield wiper. Pulse timing and "demand"
wash functions are controlled electronically on pulse
windshield wipers.
WIPER AND WSHER OPERAflON
Pulse Windshield Wiper System Fig. 1 Wiper Motor
Electronic logic circuits on a pulse wiper system's
printed circuit board establish all timing and washer
commands. When the WASH switch is pressed, the
washer sprays only during the wiper arm
outwipe and
pulsates operation for 2-1/2 seconds. Then the wiper
dry wipes for nearly
6 seconds before shutting off. See
Pulse Wiper Operation Chart, Fig.
3, for a brief de-
scription of pulse wiper system operation.
If the WASH switch is pressed for more than one
second, a (demand) wash is performed for as long as
the switch is depressed. This wash action is followed by
6 seconds of dry wipes before shut-off. With the control
switch in the
LO or HI speed position, the respective
