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 relay F1k17 . To wipe windshield dry, the motor continues to operate after the switch has
