REMOVAL/INSTALLATION OF WIPER WASHER SYSTEM

1. INSTALLATION/REMOVAL OF THE WIPER SYSTEM:

z Disconnect the negative grid of the battery;

z Assemble the wiper blade and wiper arm;

z Open the front hood;

T-38

z Place the wiper link-rod inside and concentric the fastening hole with the welded nut of car
body;

z Tighten it with 3 bolts and washers, and the tightening torque is 9N·m;

z Install the water channel guard for the front window and other parts (see car body

instruction for details);

z According to the arrow printed on the front window, align the wiper blade with the

assembling arrow on the window; place the wiper arm into the wiper arm shaft, tighten the
fastening nut of the wiper arm and in the mean time press the blade tightly without
moving;

z Tighten the wiper arm with 2 nuts with tightening torque of 16～19 Nm, and install the
guard plate.

z The installing steps are reverse to those for removal.

2. INSTALLATION/REMOVAL OF THE WASHER SYSTEM

z Install 6 fastening clips of the washing liquid tube and 1 guard sleeve;

z Install the nozzle on the front hood;

z Insert one end of the washing liquid tube into the washing liquid container, install the

washing liquid tube in the correct direction and insert the connector to the nozzle properly;

z Align the washing liquid container with the stationery jaw of car body, and tighten it with 1

nut and washer.

z The installing steps are reverse to those for removal.

Remarks

The wiper motor
does not
function.

When the
ignition switch
is turned on, turn
the wiper switch
to (intermittent
wiping), (slow
wiping), (fast
wiping),
(short-time
wiping) position,
the wiper motor
always does not
function.

(1) The power
supply circuit of
the wiper motor
is open.
(2) Poor contact
of the ignition
switch and the
wiper switch.
(3) There is an
open circuited
point in the
wiper motor.

(1) Check the circuit
of the wiper power to
see whether there is
any open circuit. If
there is, fix it
immediately.
(2) Test the voltage of
each point of the
motor winding with
multimeter, and verify
that the motor circuit
is open. If it is open,
replace the motor.

T-39

(3) Verify that the
wiper switch and the
X-contact off-load
relay function
normally. Otherwise,
replace the
corresponding parts.

The intermittent
wiping does not
function.

When the
ignition switch
is turned on, turn
the wiper switch
to (intermittent
wiping) position,
the wiper motor
does not
function
intermittently.

(1) The circuit
of the wiper
intermittent
controller is
open.
(2) The internal
part of the wiper
intermittent
controller is
damaged.

(1) Verify that the fuse
S8 in the relay box and
the wiper relay,
8/15-contact off-load
relay are normal.
(2) If the fuse and the
relay are normal,
verify that whether the
intermittent controller
circuit of the wiper is
open.
The route of the circuit
is as follows:
Turn on the ignition
switch

→ wiper motor

terminal 5F/2

→ turn

on the intermittent
gear -5F/5

→

intermittent controller
relay 1/J

→

intermittent controller
relay function.
Fuse S8 → wiper relay
terminal 8/15 → wiper
relay terminal 2/53M
→ the 2# socket of the
relay base connector S
→ green wire → wiper
motor terminal 4/53 →
wiper motor terminal
5/31 → brown/yellow
wire → grounding.
(3) If the circuit works
properly, it is the
malfunction of wiper
intermittent controller.
