Wiper Motor: Description and Operation
GF82.30-P-4104-01S Wiper Motor, Function
Function
The wiper motor (M6/1) is a DC motor with three brushes.
Depending on which pair of brushes is energized, the wiper motor (M6/1) operates at different speeds.
Cam switch
The cam switch is closed when the wiper motor (M6/1) is in the rest position. With each wiping cycle the cam switch opens and closes when the
non-actuated state is reached. This generates the signal c. 31b.
Using the circuit 31b signal, it is possible to determine whether the wiper motor (M6/1)

is operating correctly,
^
locked up, or
^
in the rest position.
