System Description
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.located in the fuse block)

to wiper motor terminal
6and
3.
Low and high speed wiper operation
Ground is supplied to wiper switch terminal
17through body groundsE11andE37.
When the wiper switch is placed in the LO position, ground is supplied

Through terminal
14of the wiper switch

to 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
16of the wiper switch

to wiper motor terminal
1.
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 terminal
14of the wiper switch

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

through terminal
13of the wiper switch

to front wiper relay terminal
3

through terminal
4of the front wiper relay

to wiper motor terminal
5

through terminal
4of the wiper motor, and

through body groundsE11andE37.
When wiper arms reach base of windshield, wiper motor terminals

5and
3are connected instead of
terminals

5and
4. Wiper motor will then stop wiper arms at the PARK position.
Intermittent operation
With variable intermittent
The wiper motor operates the wiper arms at a set interval of approximately 2 to 20 seconds. This feature is
controlled by the combination switch wiper amplifier.
When the wiper switch is placed in the INT position, ground is supplied

to front wiper relay terminal
5

from wiper switch terminal
13

through body groundsE37andE11.

to wiper motor terminal
2

through the wiper switch terminal
14

to wiper switch terminal
13

through front wiper relay terminal

The desired interval time is input

to front wiper relay terminal
1

from wiper switch terminal
20.
The wiper motor operates at low speed at the desired time interval.

EL-186

WIPER OPERATION
Without variable intermittent
The wiper motor operates the wiper arms at an interval of approximately 7 seconds. This feature is controlled
by the combination switch wiper amplifier.
When the wiper switch is placed in the INT position, ground is supplied

to front wiper relay terminal
5

from wiper switch terminal
13

to wiper motor terminal
2

through the wiper switch terminal

WASHER OPERATION
With the ignition switch in the ON or START position, power is supplied

through 10A fuse (No.21, located in the fuse block)

to washer switch terminal
5.
When the lever is pulled to the WASH/F position, ground is supplied

to washer motor terminal
2

from terminal
18of the wiper switch

through terminal
4of the wiper switch, and

through body groundsE37andE11.
Power is supplied

from terminal
3of the washer switch

to washer motor terminal
1.
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 combination switch (wiper
amplifier) in the same manner as the intermittent operation.
