WIPER MOTOR, FUNCTION - GF82.30-P-4104-01GH
The wiper arm can be driven by the motor with two speeds. The motor runs at high or low speed depending on
brush voltage present.
The cam switch switches circuit 31b from circuit 15 to circuit 31 when the windshield wiper runs through the
park position.
WIPER MOTOR, DESIGN - GF82.30-P-4104-02GH
The windshield wiper is driven by the wiper motor (M6/1) , an electric motor with three brushes and gear. The
cam switch is located on the output shaft.

REAR WIPER/WASHER SWITCH - FUNCTION - GF82.30-P-4105-01GH
The rear intermittent wipe function is started by placing the rear wiper/washer switch (S78) in the up position.
The switching contact connects the input (c) to the All Activity Module (AAM, N10) to terminal 15 (a).
The rear wash function is started by placing the switch in the down position. Power is fed to the tailgate
washer pump (M5/3) (b) from terminal 15 via the second switch contact and the AAM input (c) is
simultaneously connected to terminal 15 via the resistor (R).
As of 1.9.2000:
When the rear intermittent wipe function is activated manuallythe LED built into the rear wiper/ washer switch
(S78) will illuminate. LED illumination is controlled by the All Activity Module (AAM, N10) .

REAR WINDOW WIPER MOTOR, FUNCTION - GF82.30-P-4106-01GH
The rear window wiper motor (M6/4) is controlled by the all-activity module (AAM) (N10) Wiper
operation :
The rear window wiper is in the non-actuated position and the cam switch is therefore actuated. The relay is
actuated by the AAM. The rear window wiper motor (M6/4) starts running . The cam switch is released. The
motor then continues to run even when the relay is no longer actuated. Upon reaching the park position the cam
switch is actuated. If the relay is no longer actuated the motor is stopped by short circuiting through a coil.

REAR WASH - FUNCTION - GF82.35-P-3001GH
MODEL 163
The rear wash function is activated by placing the rear wiper/ washer switch (S78) in the down position. The
switch contact connects the tailgate washer pump (M5/3) to terminal 15. The All Activity Module (AAM)
(N10) detects the activation of the switch via the second switch contact and actuates the tailgate washer motor
(M6/4) and the tailgate washer fluid pump (M5/3) for as long as the switch is on.
The activation time for the tailgate washer fluid pump (M5/3)is limited to 15 sec. To reactivate the pump, the
button must be pressed again.
To wipe window dry, the tailgate wiper motor (M6/4) remains activated for five seconds after the switch is
released.
As described for the rear wiper function, a relay circuit in the wiper motor stops the wiper in the park position .
WINDSHIELD WASH - FUNCTION - GF82.35-P-3002GH
MODEL 163
The windshield wash function is activated by pulling the combination switch, washer switch (S4s4) towards
the steering column. The switch contact connects the washer pump (M5/1) to terminal 15R. The All Activity
Module (AAM) (N10) detects switch activation via an input that measures power supply to the washer pump
(M5/1).
If the combination switch (S4) is in the Wiper Off or Intermittent position, the AAM activates the wiper
motor (M6/1) via rela
y F1k17 . To wipe windshield dry, the motor continues to operate after the switch has
