Principles of Operation

The wiper system has four different operating modes:

off mode, low-speed mode, high-speed mode, and

speed sensitive interval mode.
In the off mode, there is no windshield wiper motor

activity, and the windshield wiper motor is in the

PARK position.
In the ON mode, the windshield wiper motor is set to

a low-speed setting. The wiper/washer switch

provides voltage to the windshield wiper motor

through the low-speed circuit. The windshield wiper

motor provides ground through a dedicated ground

circuit.
In the high-speed mode, the windshield wiper motor is

set to a high-speed setting. The wiper/washer switch

provides voltage to the windshield wiper motor

through the high-speed circuit. The windshield wiper

motor provides ground through a dedicated ground

circuit.
In the interval mode, the windshield wiper motor is set

to a low-speed setting. The windshield wiper interval

relay is activated at the beginning of each wipe and

deactivated when the windshield wiper motor park

switch reaches the run position. The interval relay is

part of the wiper/washer electrical system.
When the wiper/washer switch is in the interval

position, the windshield wipers will make a single

sweep followed by a pause. The interval frequency

can be varied by rotating the control. The frequency

will auto adjust to vehicle speed.
To engage the windshield washer, pull the knob of
