Wiper motor internal components, including permanent magnet fields, armature, brush holder, gear train and park switch, are enclosed in a two-piece
housing which is held together by ten staked extrusions. The brush holder and motor run terminals are at one end of the motor, and the gear box and park
switch at the other end, Fig. 9. Motor operation is controlled by three brushes, common, low and high speed.
When ignition is on, battery voltage is supplied to the common brush through a fuse in the fuse block. Motor speeds are determined by completing the
low or high speed brush circuit to ground at the wiper switch. Pulse wiper operation, if equipped, is controlled by a variable resistor in the wiper switch
and by a pulse module connected between the wiper motor and switch.
