A/T SHIFT LOCK
GENERAL DESCRIPTION
This circuit consists of the starter switch, stoplight switch (vehicle w/o cruise control), brake switch (vehicle
w/cruise control),
shift lock controller, stoplight, backup light and mode switch.
The shift lock system is designed not
to allow the shift lever to be shifted from the "P" position to any other
position
without depressing the brake pedal while the starter switch is turned on.
The solenoid pin at the
lower portion of the shift lever retracts when the brake pedal is not depressed, thus
causing the shift lever cam
to be locked by the link lever.

WINDSHIELD WIPER/WASHER AND REAR WIPER/WASHER
GENERAL DESCRIPTION
~ The circuit consists of the starter switch, wiper & washer switches, wiper motors, washer motors and inter­
mittent relays for both the windshield and some models the rear wipers.
When the
wiper & washer switch is turned on with the starter switch on, the battery voltage is applied to the
wiper motor to activate the wiper.
The washer
motor squirts glass cleaning fluid while the washer switch is being pushed. The intermittent relay
is used
to control motion of the wiper.
OPERATION OF WINDSHIELD WIPER MOTOR (When wiper & washer SW is at "LO" or ''I NT"
position)

HEADLIGHT WIPER/WASHER
GENERAL DESCRIPTION
The circuit consists of the starter switch, headlight wiper/washer switch, headlight wiper motor and washer
motor. By pushing the headlight wiper/washer switch, with the starter switch on, the wiper will make 5 strokes,
with washer solution applied between each of the first 4 strokes, regardless of the length of time the switch is
held down.
The washer nozzle is installed to the wiper blade, and the washer motor draws fluid from the same reservoir
as the windshield washer.
OPERATION OF HEADLIGHT WIPER

set
to ON and headlight
wiper starts to operate.
