DIRECTION INDICATORS
GENERAL
The direction indicators consist of flashing lights at front
and rear. At the front, the flashers are combined with the
parking lights and flash with white or (as from model
1969) orange light. At the rear, separate lamps are pro-
vided for the flashers, These are mounted in the same
housings as the stop lights and tail lights and flash with
orange light.
The flasher unit, which is installed under the instrument
panel, is combined with a control relay which indicates,
by means of green warning lamps on the instrument panel,
that the direction indicator is on and that both lamps are
working.
If one of the flashers fails to operate, the warning lamp
will not glow and the remaining light will flash more ra-
pidly. If the flasher unit is in good condition and correct
bulbs are fitted, the direction indicator will flash at the
rate of 60—120 flashers per minute.
The flasher unit is not adjustable. If the other parts of the
direction—indicating system (switch, wires and lamps) are
in good order, erratic flashing must be due to a faulty
flasher unit. In these circumstances, a new flasher unit
must be fitted.
As from model 1966, the flasher in cars for USA serves
also as sender for the warning flasher system. That relay
is of a special type, and — in case of replacement — must
not be confused with relays of types formerly used, In-
structions for attachment of the direction—indicator
switch and return mechanism are given below.
NOTE
The fitting of bulbs with incorrect ratings will result
in abnormal flashing frequency.

DIRECTION INDICATOR RETURN YOKE
The clearance between the return yoke and the projec-
tion on the directional indicator switch should be 0.008—
0.024 in, (0.2—0.6 mm) with the switch at neutral. Ad-
just by inserting shims between the switch and the column
stand.
NOTE
Fit the return yoke so that its center axis coincides
with the center axis of the switch housing, when
the wheels are straight ahead.

HORNS, SIGNALING DEVICE
GENERAL
The horns are mounted inside the front panel. One higti-
pitched and one low-pitched horn are harmonized to give
a high-penetration signal.
If the horns produce a discordant tone, first localize the
defective horn and adjust by turning the contact screw
marked with red paint, on the rear of the horn until a
pure note is obtained.
As from model 1972, there is only one horn mounted. It
is placed to the right, inside the front sheet.

SIGNALING DEVICE MODELS 1968 AND 1969
General
On the 1968 and 1969 models of Saab 95 and 96, the

To sound the horn, the lever is moved towards the steer-
ing wheel.

WINDSHIELD WIPERS AND
-WASHERS, HEADLIGHT
WIPERS AND -WASHERS
General
The windshield wiper motor can be set for two wiper
speeds. The higher speed is intended for fast driving in
heavy rain. During heavy snowfalls or when the windshield
is almost dry, the lower speed should be used to avoid
overloading the wiper motor.
The motor has an automatic “parking device’, which
make them stop always in a horizontal position, notwith-
standing the position they are in when they are switched
off.

WIPER MOTOR
Function
In the wiper motor the movement is transmitted to the
operating rods via a gear housing. Current for the wiper
motor is supplied by the battery through the ignition con-
tact via a fuse and switch and a contact device in the gear
housing. That device is connected during the largest part
of the working cycle, thus giving the motor two alterna-
tive earth connections, if the switch is on. Every time the
wiper blades are in their horizontal position, where they
are normally parked, the contact in the gear housing cover
is cut off. If the switch at that moment is not on, the mo-
tor stops and so will the wiper blades in this position. The
parking position can be adjusted by slackening the gear
housing bolts thus enabling the cover to be turned a little,
which moves the fixed contact plate.
Removal and installation
1. Disconnect the linkage from the crank arm on the wip-
er motor (accessible from under the instrument panel).
2. Disconnect the power leads and remove the motor re-
taining screws. Lift out the wiper motor.
Install in the reverse order.
NOTE
Check before testing, that the crank arm on the right
spindle (on R.H.D. cars, the left spindle) is turned up-
wards. If it is turned downwards, the wiper arm goes
in the wrong direction and damages the paintwork.
Lubrication
The motor armature is mounted in self-lubricating bear-
ings. The gear housing is factory-lubricated. Periodical
lubrication is not needed.

WINDSHIELD WASHER
Cars of model 1967 are fitted with a mechanical wind-
shield washer, the pump being combined with the switch
for the windshield wipers. As from model 1968, the cars
have an electric pump which is started with the same
switch as is used for the windshield wipers,

ELECTRICAL CONTROLS AND
SWITCHES
As from model 1971, the Saab V4 is equipped for cer-
tain markets with a cleaning device for the headlights.
The device consists of a wiper and washer unit driven by
separate electric motors and started with the same switch
as the windshield wipers and -washers. As from model
1972, the two washer systems has a common pump.

ELECTRICAL CONNECTION AND OPERATION,
MODEL 1971
Switch in position 0
If the ignition lock is engaged, voltage is available at the
wiper motor connections 4 and 53a respectively. The mo-
tors take up the parking position when a spring loaded
contact in each motor has broken the connection between
4 and 2 in the windshield wiper motor and between 53a
and 53 in the headlight wiper motor. The motors start
very quickly when connections 1 and 31b respectively
have been actuated by the contact device and thus shor-
ted the rotor windings. This is necessary in order for the
motor to have time to stop during the time the cam is ac-
tuating the contact. Otherwise, the motor would conti-
nue to rotate despite the switch being switched off, es-
pecially when the wipers move easily and the voltage
across the motor is high.
Switch in position 1
Current goes only to the windshield wiper motor (low
speed) via connections 54 and 53 on the switch.
