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 .
