Wiper After Wash Mode

When the driver presses the wash button for more than 1/2 second and then releases it, the wiper will continue to run for 2 additional wipe cycles.

The wiper system utilizes the BCM to provide intermittent operation. The low and high speed are run directly from the multifunction switch. The BCM controls the intermittent relay to change the wiper delay as the multifunction switch input changes. The BCM uses vehicle speed input to double the usual delay times below 10 MPH.
