System Description
NBEL0318
WIPER OPERATION
NBEL0318S01
The front wiper switch is controlled by a lever built into the combination switch.
There are three wiper switch positions:
쐌
LO speed
쐌
HI speed
쐌
INT (Intermittent)
With the ignition switch in the ACC or ON position, power is supplied
쐌
through 20A fuse [No. 19, located in the fuse block (J/B)]
쐌
to front wiper motor terminal 1, and
쐌
to front wiper switch terminal 15.
Low and High Speed Wiper Operation
NBEL0318S0101
Ground is supplied to front wiper switch terminal 17 through body grounds E13 and E41.
When the wiper switch is placed in the LO position, ground is supplied
쐌
through terminal 14 of the front wiper switch
쐌
to front wiper motor terminal 5.
With power and ground supplied, the front wiper motor operates at low speed.
When the front wiper switch is placed in the HI position, ground is supplied
쐌
through terminal 16 of the front wiper switch
쐌
to front wiper motor terminal 3.
With power and ground supplied, the front wiper motor operates at high speed.
Auto Stop Operation
NBEL0318S0102
With front wiper switch turned OFF, front wiper motor will continue to operate until wiper arms reach windshield
base.
When wiper arms are not located at base of windshield with front wiper switch OFF, ground is provided
쐌
from terminal 14 of the front wiper switch
쐌
to front wiper motor terminal 5, in order to continue front wiper motor operation at low speed.
Ground is also supplied
쐌
to terminal 13 of the front wiper switch
쐌
through front wiper motor terminal 4
쐌
through terminal 6 of the front wiper motor, and
쐌
through body grounds M77 and M111.
When wiper arms reach base of windshield, front wiper motor terminals 1 and 4 are connected instead of ter-
minals 4 and 6. Wiper motor will then stop wiper arms at the PARK position.
Intermittent Operation
NBEL0318S0103
The front wiper motor operates the wiper arms one time at low speed at a set interval of approximately 2 to
13 seconds. This feature is controlled by the wiper amplifier built into the front wiper switch.
The desired interval time is input to wiper amplifier (INT VR) from wiper volume switch built into the front wiper
switch.
When the front wiper switch is placed in the INT position, ground is supplied
쐌
to wiper amplifier (INT SW)
쐌
from front wiper switch terminal 17
쐌
through body grounds E13 and E41,
쐌
to front wiper motor terminal 5
쐌
through the front wiper switch terminal 14 and
쐌
through wiper amplifier (OUTPUT).
WASHER OPERATION
NBEL0318S02
With the ignition switch in the ACC or ON position, power is supplied
쐌
through 20A fuse [No. 19, located in the fuse block (J/B)]
쐌
to front washer motor terminal 1.
When the lever is pulled to the WASH position, ground is supplied

쐌
through terminal 18 of the front wiper switch
쐌
through terminal 17 of the front wiper switch, and
쐌
through body grounds E13 and E41.
With power and ground supplied, the front washer motor operates.
When the lever is pulled to the WASH position for one second or more, the front 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.

WIPER ARMS
NBEL0320S01
1.
Prior to wiper arm installation, turn on wiper switch to operate
wiper motor and then turn it “OFF” (Auto Stop).
2.
Lift the blade up and then set it down onto glass surface to set
the blade center to clearance “L
1
” & “L
2
” immediately before
tightening nut.
3.
Eject washer fluid. Turn on wiper switch to operate wiper motor
and then turn it “OFF”.
4.
Ensure that wiper blades stop within clearance “L
1
” & “L
2
”.
Clearance “L
1
”: 29 - 39 mm (1.14 - 1.54 in)
Clearance “L
2
”: 32 - 42 mm (1.26 - 1.65 in)
쐌
Tighten wiper arm nuts to specified torque.
Front wiper: 21 - 26 N·m (2.1 - 2.7 kg-m, 15 - 20 ft-lb)
SEL024J
쐌
Before reinstalling wiper arm, clean up the pivot area as
illustrated. This will reduce possibility of wiper arm loose-
ness.
