Low Speed

In the LO position, the Wiper/ Washer Switch supplies voltage to the BRN (96) wire and the Pulse/ Speed/ Wash Control. The Pulse/ Speed/ Wash Control provides ground to the Park/ Run Relay which is energized and supplies voltage to the brushes of the Wiper Motor. The wipers run at low speed until they are turned off.
