Washer
The windshield wiper functions are operated by moving the switch up or down. Flick wipe is selected by pushing the
switch up against the spring pressure. The flick wipe switch contact is connected on a single wire to the windshield
wiper delay Electronic Control Unit (ECU) and ground. When the switch is operated the circuit is completed between the
delay ECU and ground. With the circuit completed the wipers operate for as long as the switch contact is made.
Intermittent is selected by pushing the wiper switch down, to the detent position, the wipers operate at a delay period,
which is controlled by the windshield wiper delay ECU. The wipers remain in the intermittent mode until the wiper switch
is moved to the off or slow/fast speed positions. The intermittent switch contact is connected between the delay ECU
and ground. When the switch is moved to the intermittent position the circuit is completed. With the circuit completed,
the wipers operate in intermittent for as long as the switch contact is made.
Slow speed operation is selected by pushing the wiper switch up, to the second detent position. The wipers operate at
slow speed until the wiper switch is moved to the off, intermittent or fast speed positions. The slow speed switch
contact is connected between the delay ECU and ground. When the switch is moved to the slow speed position the
circuit is completed. With the circuit completed, the wipers operate at slow speed for as long as the switch contact is
made.
Fast speed operation is selected by pushing the wiper switch up, to the second detent position. The wipers operate at
fast speed until the wiper switch is moved to the off, intermittent or slow speed positions. The fast speed switch contact
is connected between the delay ECU and ground. When the switch is moved to the fast speed position the circuit is
completed. With the circuit completed, the wipers operate at fast speed for as long as the switch contact is made.
The windshield washers are operated by pressing the button on the end of the wash/wipe stalk located on the RH side of
the steering column. When the button is pressed, the washers operate immediately and stop immediately the button is
released. The washer button contact is connected between the delay ECU and ground. When the button is pressed the
circuit is completed. With the circuit completed, the washers operate for as long as the contact is made.
IGNITION SWITCH
The ignition switch is located in the LH end of the steering column assembly. The switch is held in the column lock
casting with 2 locking tabs, which engage in slots in the column lock casting.
The switch has a slot, which provides for the location of the drive shaft. The drive shaft passes through the column lock.
This shaft is rotated by the driver when the ignition key is turned in the key barrel. This rotation turns a drum inside the
ignition switch, which moves 2 electrical contacts to select the required ignition position. A spring loaded ball locates in a
seat for each of the 3 ignition switch positions, allowing the driver to feel when the required position is reached.
