Windshield Wiper System
Early
production vehicles equipped with
the
Dauntless V-6
engine
have
two
single speed wind
shield wiper motors mounted above
the
windshield inside
the
vehicle. The wiper motors
are
operated
and
controlled
by a
switch located
on the
instru
ment panel.
Current
production vehicles with stationary wind
shield have
a
two-speed
electric windshield wiper motor mounted below
the
windshield outside
the
vehicle on the driver's side. The wiper motor switch is located
on the
instrument panel
to the
left
of
the steering column.

Two-Speed Wiper Motor
The
two-speed
electric wiper motor
is
operated and
controlled
by a
turn
type, three poled, dash switch,
containing
a 6
amp. circuit breaker.
Current
flow
is directed from
the
battery through
the
ignition
switch
to the
wiper dash switch assembly
to the
two-speed
wiper motor, which passes current from the designated motor brush (high,
low or
park)
to
the armature circuit
to
ground.
