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 been released until the AAM detects three operations of the cam-operated switch.
