REAR WIPER AND WASHER CIRCUIT
OPERATION
<Low-speed wiper>
l
When the rear wiper switch is placed in the ON
position with the ignition switch in the ACC or
ON position, wipers operate continuously at low
speed.
<Auto wiper stop>
l
When the rear wiper switch is placed in the OFF
position, the cam contacts of wiper motor cause
current to flow through the auto wiper stop
circuit, allowing the wiper blades to cycle before
they reach to the stop positions.
<Intermittent wiper>
l
When the rear wiper switch is placed in the INT
position with the ignition switch in ACC or ON
position, the rear intermittent wiper relay is
energized causing the rear intermittent wiper
relay contacts to close and open repeatedly.
l
When the contacts are closed, the wiper motor
is energized.
l
When the rear wiper motor is energized, the rear
intermittent wiper relay contacts open; howev-
er, the cam contacts keep the rear wiper motor
energized until the wiper blades return to their
stop position.
