Wiper/Washer System Operation

The body control module (BCM) is part of the windshield wiper motor system and controls the wiper motor operation. The windshield wiper motor is a 2 speed motor. Windshield wiper intermittent operation is a low speed wiper motor function with a variable delay interval between the wipe cycles. The intermittent interval is controlled through a series of resistors within the wiper/washer switch. During intermittent wiper operation the windshield wiper switch low signal circuit is at the same circuit used for LOW operation.
