Intermittent Wipers

The BCM sends a signal to the wiper/washer switch to monitor the request for the intermittent wipers. When the wiper/washer switch is placed to the intermittent position, the signal is routed to the return circuit, pulling the signal low indicating a request for the intermittent wiper mode. When BCM detects the intermittent wiper mode request, it monitors a separate circuit for the interval timing.

The interval timing signal to the wiper/washer switch passes through a rheostat within the wiper/washer switch. The signal varies, based on the 6 intermittent settings. The 6 intermitting settings are:

AUTO 1/INT 1
AUTO 2/INT 2
AUTO 3/INT 3
AUTO 4/INT 4
AUTO 5/INT 5
AUTO 6/INT 6
