Intermittent Operation
WARNING: This page is about a different car, the 2004 Chevrolet Monte Carlo and 2004 Chevrolet Impala. However, it is still accessible from the selected car via links, so may be relevant.
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.
