Wiper/Washer Systems: Operation: Notes
The wiper motor has 3 brushes that are referred to as common, low speed and high speed. When the ignition switch is in the "ON" position, the power feed circuit is completed to both low and high speed fixed contacts in the steering column switch. The low and high speed brushes are connected to the column switch through terminals 1 and 2. The armature is grounded through the common brush via the ground strap.
