Intermittent Operation

Windshield wiper intermittent 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 resistors within the wiper/washer switch. During intermittent wiper operation, the windshield wiper switch signal 1 circuit is reduced through the resistors.

When the wiper / washer switch is in the DELAY position, two different voltages are applied to the windshield wiper module to operate the windshield wiper motor in a intermittent mode at low speed.

• Reduced voltage is supplied through a resistor within the switch to the windshield wiper signal 2 circuit.
• Variable reduced voltage, dependent upon windshield wiper switch position, is applied to the windshield wiper signal 1 circuit.
