1 General Information
This Section describes the service, testing procedures and diagnosis for the wipers and washer systems as well as the
horns fitted to MY 2005 VZ Series vehicles.
1.1 Front Wiper Assemblies
Wiper Assemblies
The two front wiper assemblies consist each of a wiper blade secured to a wiper arm which is attached to a drive spindle
part of linkages attached to the plenum cham ber an d driven by the front wiper motor assembly.
A one piece plenum cover is fitted to Seda n, W agon and Utility vehicles. The front washer nozzle assemblies and part of
the front washer hose are secured to the plenum cover. An air deflector and a water deflector are attached to the plenum
cover.
A two pieces plenum cover is fitted to Coupe vehicles and the washer nozzle assemblies a re mounted in the hood
assembly. A water deflector is attached to the plenum chamber.
The front wiper assemblies are operated via the wipers and washers control s witch assembl y fitted to the steering
column. The operation inclu ding the intermittent dwell function is controlled by the body control module (BCM), refer to
Section 12J Body Control Module.
The wipers and washers control switch in the variable intermittent position decreases or increases the frequency the
wiper motor is actuated, through the détente. The wipers and washers control s witch has seven increments, and the
dwell time is determined via a combination of vehicle road speed and the wiper control stalk.
Wiper Motor
The front wiper motor assembly operates in one direction to drive the front wiper arms for the wiping of the windshield.
The front wiper motor assembly has three modes of operati on:
• intermittent wipe cycle,
• continuous low speed wipe mode, and
• continuous high speed wipe mode.
With the ignition switch in the ACC or ON position, and the wipers and washers control switch is moved to the position 1
or 2, power is directly supplied to the front wiper motor for low or high speed wipe operation. When the wipers and
washers control switch is moved to the INT position, power is supplied to the front wiper motor via the bo dy control
module (BCM) for intermittent wipe operatio n.
When the wipers and washers control switch is moved to the OFF position, the park s witch included in the front wiper
motor assembly supplies power to the front wiper motor via the BCM until the front wiper arms reach the park position. At
this point the park switch opens and disconnects the power supply to the front wiper motor and the front wiper arms
remain stationary at the park position.
For a complete wiring diagram of the front wiper system, refer to:
• 3.2 Wiring Diagram – Front Wiper/Washer, Except Wagon, or
• 3.3 Wiring Diagram – Front Wiper/Washer, Wagon, or
• 3.4 Wiring Diagram – Front Wiper/Washer, AWD Wagon.
Wipers, Washers and Horn Page 12N–8
Page 12N–8
1.2 Rear Wiper Assembly, Wagon
Wiper Assembly
The rear wiper assembly consists of a wiper blade secured to a wiper arm which is attached directly to the rear wiper
motor driveshaft.
The rear wiper motor assembly is attached to the liftgate ass embl y and drives the rear wiper arm assembly directly
through the motor driveshaft.
The rear wiper assembly is operated via the wipers and washers control switch assembly fitted to the steering column,
the operation is controlled by the BCM, refer to Section 12J Body Control Module.
With the ignition switch in the ON or ACC position the functions of the rear wiper are as follows:
• When the rear wiper switch is ON and the ne utral or drive gear is selected, the rear wiper activates intermittently at
8 second intervals.
• When the rear wiper switch is ON and the reverse gear is selected, the intermittent operation of the rear wiper goes
into continuous wipe mode until t he reverse gear is deselected.
• When the rear washer is selected, the rear wiper action is continuous wipe mode until the rear washer switch is
released.
Wiper Motor
The rear wiper motor is install ed in the liftgate and is directly linked to the rear wiper arm via a driveshaft.
With the ignition switch in the ACC or ON position and the wipers and washers control switch is moved to the rear wiper
ON position, power is supplied to the rear wiper motor via the body control module (BCM) and the rear wiper relay.
When the wipers and washers control switch is moved from the ON to OFF position, the park switch inclu ded in the rear
wiper motor assembly supplies power to the rear wiper motor until the rear wiper arm reaches the park position. At this
point the park switch contacts open and disconnects the power supply to the rear wiper motor and the rear wiper arm
remains stationary at the park position.
For a complete wiring diagram of the rear wiper system, refer to 5.2 Wiring Diagram – Rea r W iper/Washer.
Wipers, Washers and Horn Page 12N–9
Page 12N–9
1.3 Rear Wiper Assembly, AWD Wagon
Rear Wiper Assembly
The rear wiper assembl y cons ists of a wiper blade secured to the rear wiper arm which is attached to the rear wiper
motor shaft.
The rear wiper motor assembly is attached to the liftgate ass embl y and drives the rear wiper arm assembly directly
through the motor driveshaft.
A rear wiper ramp is located below the liftgate window to provide support for the wiper arm in the park position.
Protective clear PVC tape is applied to the liftgate where the wiper blade is resting.
The rear wiper assembly operation is not controlled by the BCM as in other Wagon ve hicles. The control functions have
been transferred to a rear wiper control module (A122).

When the rear wiper has been operating,
before turning off the ignition switch ensure
the rear wiper arm is in the offscreen park
position. If failing to do so, the situation could
arise where the liftgate window could be
opened with the rear wiper stopped on the
glass panel and vehicle damage co uld occur.
When the rear wiper is not in operation it parks below the liftgate window, the arm (10) resting on th e rear wiper ramp (9),
refer to Figure 12N – 1. This parking position enables the hinged liftgate window to be opened o utward with the rear
wiper positioned clear of the glass panel.
With the ignition switch in the ON or ACC position and the li ftgate is open, when the wipers and washers control switch is
moved to the rear wiper ON position, the rear wiper will not operate. For the rear wiper to be operational again, close the
liftgate, then move the wipers and washers control switch in the OFF position and back to the rear wiper ON position.
The same condition applies if the liftgate window is open when the wipers and washers control switch is moved to the
rear wiper ON position.
Wipers, Washers and Horn Page 12N–10
Page 12N–10
If the rear wiper is operating, the liftgate windo w can not be ope ned.
If the liftgate window is closed and the liftgate only is opened while the rear wiper is operating, the wipe mode will not
stop. Move the wipers and washers control switch in the OFF position to stop the operation of the rear wiper; the
operation can not be restarte d before the liftgate is closed.
With the ignition switch in the ON or ACC position the functions of the rear wiper are as follows:
• When the wipers and washers control switch is moved to the rear wiper ON position, the rear wiper activates
intermittently at 9 second intervals.
• When the wipers and washers control switch is moved to the rear wiper ON position and the reverse g ear is
selected, the intermittent operation of the rear wiper goes into continuous wipe mode until the reverse gear is
deselected.
• When the rear washer is selected, the rear wiper action is continuous wipe mode until the rear washer switch is
released.
• When the rear wiper is operating and the rear washer is selected, the intermittent operation of the rear wiper goes
into continuous wipe mode until the rear washer switch is released.
• When the wipers and washers control switch is moved from the rear wiper ON to OFF position, the rear wiper
suspends for one second in the furthest on-screen park position then returns to the off-screen park position.
Rear Wiper Control Module
The rear wiper control module (1) is installed in the liftgate. It controls the various functions of the rear wiper / washer.
The rear wiper control modul e also provides a link with the liftgate window release actuator (2), the liftgate window
microswitch (3) (within the latch) and the liftgate switch (4) refer to Figure 12N – 1.
For a description and functions of the liftgate window release actuator, liftgate window microswitch and liftgate switch
refer to Section 1A4 Hood, Rear Compartment Lid, Liftgate and Endgate.
The rear wiper module will inhibit the rear wiper operation if the liftgate and/or the liftgate window are open.
The rear wiper module triggers the liftgate window release. The liftgate window release actuator solenoid is inhibited if
the rear wiper switch or the rear washer switch is ON.
Before permitting the wiper motor to operate, the rear wiper
control module (1) monitors the positions of both the liftgate
and the liftgate window latch.
The rear wiper control module also monitors the rear wiper
three park positions:
• rear wiper offscreen park position (2),
• rear wiper onscreen park position (3), and
• rear wiper furthest onscreen park position (4).
Figure 12N – 2
Wipers, Washers and Horn Page 12N–11
Page 12N–11
Rear Wiper Motor Assembly
The rear wiper motor assembly (5) is introduced to suit the opening liftgate window and offscreen parking (6) of the rear
wiper arm, refer to Figure 12N – 1.
The rear wiper motor assembly has forward park and reverse park limit switches mec ha nically linked to the wiper arm
driveshaft. The forward park limit switch determines when the wiper arm is at the start of the wipe sweep (7) (onscreen
park position), while the revers e park limit switch determines when the wiper arm has reached the full wipe sweep (8)
(furthest onscreen park position).
The rear wiper motor assembly operates e ith er in the forward direction to drive the rear wiper arm for the wiping of the
liftgate window, or in the reverse direction to drive the re ar wiper arm to the offscreen park position, refer to
Figure 12N – 3.
Rear Wiper Ramp
The rear wiper ramp (9) is attached to the liftgate bel ow the liftgate window for the offscreen parking of the rear wiper
arm (10), refer to Figure 12N – 1.
Functional Operation
For the rear wiper assembly functional oper ation description, refer to Figure 12N – 3.
For a complete wiring diagram of the rear wiper system, refer to 6.2 Wiring Diagram – Rea r W iper/Washer and
6.3 Wiring Diagram – Rear Wiper Control Module.
Intermittent Wipe Cycle Operation
A wipe cycle consists of the rear wiper arm movement from the onscreen park position (2) to the furthest onscreen park
position (3) and back to the onscreen park position (2).
With the ignition switch in the ACC or ON position and the wipers and washers control switch is moved to the rear wiper
ON position, the rear wiper motor operates in the forward direction (6) for one wipe cycle and then waits for 9 seconds
before resuming the next wipe cycle. This procedure is repeated until the wipers and washers control switch is moved to
the OFF position.
During this cycle, the rear wiper control module suppl ies power to the rear wiper motor. The forward park limit switch (5)
in the rear wiper motor opens when the rear wiper arm leaves the onscreen park position (2) and moves in the forward
direction (6) towards the furthest onscreen park position (3). The reverse park limit switch (4) in the motor closes when
the rear wiper arm reaches the furthest onscreen p ark position (3), then it opens when the rear wiper arm leaves this

between the furthest onscreen park position (3) and the onscreen park pos ition (2). The reverse park limit switch (4) and
the forward park limit switch (5) in the rear wiper motor close and re-op en alternatively as the rear wiper arm reaches the
two park positions (2 and 3). The rear wiper control module supplies constant power to the rear wiper motor.
When the wipers and washers control switch is released from the forward position the following occurs.
• If the rear wiper/washer switch is in the OFF position, the rear wiper motor continues to operate in the f orward
direction (6) until the rear wiper arm reaches the furthest onscreen park position (3) where it stops. The reverse
park limit switch (4) in the motor closes when the rear wiper arm reaches the furthest onscreen park position (3)
and the rear wiper arm remains stationar y for 1 second. Then the rear wiper control modul e reverses polarity to the
rear wiper motor which turns in the reverse direction (7). The reverse park limit switch (4) opens when the rear
wiper arm leaves the furthest onscreen park position (3) and moves al l the way to the offscreen park position (1).
• If the rear wiper/washer switch is in the ON position, the rear wiper motor continues to operate in the forward
