Operation CHARM: Car repair manuals for everyone.

Low Operation

In the LO position, the Wiper/Washer Switch supplies battery 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 battery voltage to the brushes of the Windshield Wiper Motor Module. The wipers run at low speed until they are turned off.
