Intermittent Operation

Windshield wiper delay operation is a low speed wiper motor function with a variable delay interval between the wiper motor cycles. The delay interval is determined by a series of 5 resistors within the wiper/washer switch. The body control module (BCM) monitors the voltage on the wiper switch low signal circuit to determine the delay interval between the low speed wiper motor cycles.

If the wiper switch is moved from one delay interval to another, the BCM will command an immediate wipe cycle, and reset the delay timer.
