Code B3703 Description

The intermittent switch in the windshield wiper washer switch is a voltage divider connected across the Body Control Module (BCM) inputs circuits windshield wiper switch signal circuit and windshield wiper switch low reference circuit. The front wiper relay is energized by the BCM switching the front wiper relay control circuit to ground. The Diagnostic Trouble Code (DTC) sets when the windshield wiper switch signal circuit is greater than 4.71 volts, open or shorted to voltage.
