Wiper and Washer Systems: Description and Operation
DESCRIPTIONThe Interval Wiper/Washer allows the driver to select "LO", "HI" or "Interval" (INT) wipe. In "INT", the wipes can be spaced one second to fifteen seconds apart.
OPERATION
With the Wiper Switch in the "LO" or "HI" position during washer operation, normal wipe action occurs. If the Wiper Switch is in the "OFF" or "INT" position during washer operation, the wipers operate in "LO". The wipers will continue to operate in "LO" for several cycles after the washer button is released to dry off the windshield. The wipers then return to "OFF" or "INT" operation.
During Interval operation, the wipers make single low speed wipes separated by a variable length pause.
When parking is complete, the wiper motor is braked to a stop by shunting the L and C terminals of the motor through the wiper motor switch. Braking occurs when the wiper motor switch moves to the "PARK" position. The L terminal of the wiper motor is connected to terminal C through the "PARK" contact of the motor switch and the de-energized contacts of the wiper control module relays.
