System DescriptionNJEL0456WIPER OPERATIONNJEL0456S01The wiper switch is controlled by a lever built into the combination switch.
There are three wiper switch positions:
+LO speed
+HI speed
+INT (Intermittent)
With the ignition switch in the ON or START position, power is supplied
+through 20A fuse [No. 25, located in the fuse block (J/B)]
+to front wiper motor terminal 5 and front wiper relay terminal 2.
Low and High Speed Wiper OperationNJEL0456S0101Ground is supplied to wiper and washer switch terminal 17 through body grounds E30 and E73.
When the wiper switch is placed in the LO position, ground is supplied
+through terminal 14 of the front wiper and washer switch
+to front wiper motor terminal 2.
With power and ground supplied, the wiper motor operates at low speed.
When the wiper switch is placed in the HI position, ground is supplied
+through terminal 16 of the front wiper and washer switch
+to wiper motor terminal 1.
With power and ground supplied, the wiper motor operates at high speed.
Auto Stop OperationNJEL0456S0102With wiper switch turned OFF, wiper motor will continue to operate until wiper arms reach windshield base.
When wiper arms are not located at base of windshield with wiper switch OFF, ground is provided
+from terminal 14 of the front wiper and washer switch
+to front wiper motor terminal 2, in order to continue wiper motor operation at low speed.
Ground is also supplied
+through terminal 13 of the front wiper and washer switch
+to front wiper relay terminal 3
+through terminal 4 of the front wiper relay.
+to front wiper motor terminal 3
+through terminal 4 of front wiper motor
+through body grounds E30 and E73.
When wiper arms reach base of windshield, front wiper motor terminals 3 and 5 are connected instead of ter-
minals 3 and 4. Wiper motor will then stop wiper arms at the STOP position.
Intermittent OperationNJEL0456S0103The front wiper motor operates the wiper arms one time at low speed at a set interval of approximately 1 to
13 seconds. This feature is controlled by the wiper amplifier (INT SW) combined with front wiper switch.
When the wiper switch is placed in the INT position, ground is supplied to wiper amplifier (WIPER SW INT)
and (ACC).
The desired interval time is input to wiper amplifier (INT VR) from wiper volume switch combined with front
wiper and washer switch.
Then intermittent ground is supplied
+from body grounds E30 and E73
+through terminal 5 of front wiper relay,
+through terminal 3 of front wiper relay,
+through terminal 13 of front wiper switch and,
+through terminal 14 of front wiper switch
+to terminal 2 of front wiper motor.
The desired interval time is input
+to front wiper relay terminal 1
+from terminal 20 of front wiper switch

WASHER OPERATIONNJEL0456S02With the ignition switch in the ON or START position, power is supplied
+through 10A fuse [No. 27, located in the fuse block (J/B)]
+to front wiper switch terminal 5.
When the lever is pulled to the WASH/F position, ground is supplied
+from body grounds E30 and E73,
+through terminal 4 of the front wiper switch, and
+through terminal 18 of the frotn wiper switch
+to front washer motor terminal 2.
With power and ground supplied, the washer motor operates.
When the lever is pulled to the WASH position for one second or more, the wiper motor operates at low speed
for approximately 3 seconds to clean windshield. This feature is controlled by the wiper amplifier in the same
manner as the intermittent operation.
