Low-Speed Windshield Wipers

Low speed is activated when the windshield wiper/washer switch supplies specific ground inputs to the windshield wiper motor module. The windshield wiper motor module then supplies ground for the run/park relay, activating the low-speed mode, sending voltage to the low-speed side of the motor, activating the low-speed mode. Low-speed mode is exited by selecting a different state on the switch. When the switch is placed in the OFF position, the motor continues to operate until the motor returns to the park position and the Hall-effect sensor senses the motor magnet. The output to the run/park relay deactivates the relay and disconnects the voltage to the motor.
