SERVICE POINTS OF REMOVAL
5. WIPER MOTOR
Uncouple the linkage and motor (with the wiper motor
pulled slightly outward).
Caution
Because the installation position of the crank arm and the
motor determine the wiper auto stop angle, do not disas-
semble them unless it is necessary to do so. If the crank arm
must be removed from the motor, remove it only after
marking their mounting positions.

2. INSTALLATION OF WIPER ARMS
Install the wiper arm to the pivot shaft so that the wiper
blade’s stop position is the position shown in the illustra-
tion.
INSPECTION
WIPER MOTOR
Disconnect the wiring connector from the wiper motor and
connect battery to the wiper motor connector to check that
the @viper motor runs.
LOW SPEED OPERATION CHECK
Connect battery ( + ) to terminal 1 and battery ( - ) to terminal 3
and check that the motor runs at low speed.
HIGH SPEEID OPERATION CHECK
Connect battery (+) to terminal 1 and battery (-) to terminal 4
and check that the motor runs at high speed.
AUTOMATIC STOP OPERATION CHECK
(1) Connect battery ( +) to terminal 1 and battery ( -) to
terminal 3 to run the motor at low speed.
(2) Disconnect terminal 1 during operation to stop the motor.

to terminal 1 and battery (-) to the wiper motor bracket to
check that the motor starts to run at low speed and then
stops.
INTERMITTENT WIPER RELAY
Remove the intermittent wiper relay (located at the upper part
of the left side cowl side trim).

REMOVAL AND INSTALLATION
INTERMITTENT OPERATION CHECK
(1) Cpnnect the battery and the test light to the relay, as
shown in the figure.
(2) l&ert a variable resistance between terminal 8 and battery
(1) (VR = O-50 kfl)
(3) The condition is normal if, when the battery’s negative (-)
terminal is connected to terminal 7, the test light illumi-
nates at the same time, and thereafter, in accordance with
the value of the variable resistance, stops illumination
(approx. 1.5 sec. - approx. 10.5 sec.) and then illuminates
(approx. 1 sec.) over and over again.
WASHER INTERLOCK OPERATION CHECK
(1) Connect the battery and the test light’ to the relay, as
shown in the .figure.
(2) When terminal 3 is connected to the battery’s negative (-)
terminal, the test light will illuminate approximately 1
s’econd thereafter, and then there will be a release for
a’bout seconds after connecting to the battery’s negative
( - ) terminal.
The condition is normal if about 3 seconds thereafter the
test light stops illumination. (3
