Wiper System: Notes

The wiper system provides the driver with the normal wiper (low and high speeds), intermittent wipe, wipe after wash, headlamp washers and pulse wipe functions. The driver selects the wiper function via the resistive multiplexed stalk switch mounted on the steering column. The BCM uses input signal from the wiper stalk switch, wiper motor park switch, and the washer switch to control the wipe system. The Body Control Module (BCM) then controls the relays and timing functions to provide the driver selected features.
