System DescriptionEKS0032N
WIPER OPERATION
The 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. 6, located in the fuse block (J/B)]

to front wiper motor terminal 2.
Low and High Speed Wiper Operation
Ground is supplied to front wiper and washer switch terminal 17 through body grounds E24 and E50.
When the wiper switch is placed in the LO position, ground is supplied

through front wiper and washer switch terminal 14

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 front wiper and washer switch terminal 16

to front wiper motor terminal 5.
With power and ground supplied, the wiper motor operates at high speed.
Auto Stop Operation
With 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 front wiper and washer switch terminal 14

to front wiper motor terminal 3, in order to continue wiper motor operation at low speed.
Ground is also supplied

through front wiper and washer switch terminal 13

to front wiper motor terminal 4

through terminal 1 of the front wiper motor terminal 1 and

through grounds E24 and E50.
When wiper arms reach base of windshield, front wiper motor terminals 2 and 4 are connected instead of ter-
minals 1 and 4. Wiper motor will then stop wiper arms at the STOP position.
Intermittent Operation

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 front wiper and washer switch terminal 14

to front wiper motor terminal 3
The wiper motor operates at low speed at the desired interval.
