System Description/SedanNJEL0057WIPER OPERATIONNJEL0057S01The 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 1.
Low and High Speed Wiper OperationNJEL0057S0101Ground 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 3.
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 2.
With power and ground supplied, the wiper motor operates at high speed.
Auto Stop OperationNJEL0057S0102With 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 3, 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 motor terminal 6
+through terminal 4 of the front wiper motor, and
+through body grounds E30 and E73.
When wiper arms reach base of windshield, front wiper motor terminals 1 and 6 are connected instead of ter-
minals 4 and 6. Wiper motor will then stop wiper arms at the STOP position.
Intermittent OperationNJEL0057S0103The 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 and washer
switch.
When the wiper switch is placed in the INT position, ground is supplied to wiper amplifier.
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
+through wiper amplifier (OUTPUT) and
+through terminal 14 of front wiper and washer switch
+to front wiper motor terminal 3
The wiper motor operates at low speed at the desired interval.
WASHER OPERATIONNJEL0057S02With the ignition switch in the ON or START position, power is supplied
