Front Wiper System

PURPOSE
The Interval Governor allows the driver to select "LO", "HI" or Interval (INT) wiper operation. In "INT", the wiper sweeps can be separated by one second to fifteen seconds.

OPERATION
During washer operation, normal wiping action continues with the wiper switch in "LO" or "HI" position. If the wiper switch is in the "INT" or "OFF" position, the wipers will operate at low speed. Low speed operation will continue for a few sweeps after the WASH switch is released. Wiper operation then returns to "INT" or "OFF".

When the wiper switch is moved to "OFF", the wipers will continue to sweep until the wipers reach the park position. Parking is completed when the motor is braked to a stop by shunting the L and C terminals of the motor through circuits 63 and 28 of the wiper motor switch.

Braking occurs when the wiper motor switch moves to the "PARK" position. The L terminal of the motor is connected to terminal C through the PARK contact of the motor switch and the contacts of the de-energized wiper control module relays.
