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.
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 operationat low speed.
Ground is also supplied
through terminal 13 of the front wiper and washer switch
to front wiper motor terminal 4
through terminal 3 of front wiper motor
through body grounds E30 and E73.
When wiper arms reach base of windshield, front wiper motor terminals 4 and5 are connected instead of ter-
minals 4 and 3. 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.
When the wiper switch is placed in the INT position, intermittent ground issupplied
through wiper amplifier (OUTPUT) and
through terminal 14 of front wiper and washer switch
to front wiper motor terminal 5.
The wiper motor operates at low speed at the desired interval.
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.
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)]
through front wiper switch terminals 15 and 18.
to front washer motor terminal 1.
