Front
Low SpeedWith the ignition switch in RUN, battery voltage is applied to the windshield wiper motor. When you move the wiper switch to LO, the low speed winding of the motor is grounded through the low contact of wiper washer switch, and the wipers run at low speed.
Park/Off
When you turn the wiper switch off, the integrated control unit provides ground for the windshield wiper motor. When the cam switch on the motor signals the integrated control unit that the wipers are in the park position, the control unit removes the ground from the motor and the wipers stop in the park position.
High Speed
When you move the wiper switch to HI, the high speed windings of the windshield wiper motor are grounded through the high contact of the front/rear wiper/washer switch, and the wipers run at high speed.
Intermittent
When you move the windshield wiper switch to INT, battery voltage is applied through the GRN wire to the integrated control unit. The integrated control unit grounds the low speed windings of the wiper motor. The wipers then make a single sweep approximately every five seconds.
Mist
When you push the wiper/washer lever down and hold it, the high speed winding of the windshield wiper motor is grounded through the MIST contact in the wiper/washer switch. The wipers sweep at high speed until the lever is released. The Park/Off function then takes over and the wipers stop in the park position.
Washer
When you pull the windshield washer switch toward you, battery voltage is applied to the windshield washer motor. The motor pumps fluid on the windshield and the wipers run at low speed until you release the lever. On Canadian models with combined wiper/washer operation, the integrated control unit will sense power at the GRN/BLK wire terminal and run the wiper motor. The wipers will make one more sweep after the lever is released.
