With Intermittent

With the ignition switch in ON or START battery voltage is applied to the windshield wiper/washer switch and windshield wiper motor through fuse CB-11.

Low Speed
When you push the wiper switch lever down to the first detent (LO), battery voltage is applied to the LO winding of the wiper motor, and the wipers run at low speed.

Park/Run
When you move the wiper switch lever to OFF, battery voltage is supplied through fuse CB-11 and the wiper motor, intermittent wiper relay, and wiper switch to the LO winding of the wiper motor. When the switch on the motor reaches the PARK position, battery voltage is removed from the circuit and the wipers stop in the PARK position.

High Speed
When you push the wiper switch lever down to the third detent (HI), battery voltage is applied to the HI winding of the wiper motor, and the wipers run at high speed.

Intermittent
When you push the wiper switch down to the first detent (INT), battery voltage is applied to the intermittent wiper relay. This momentarily energizes the relay, applying battery voltage to the LO winding of the wiper motor which moves the wipers from the PARK position to the RUN Position. After one sweep, the PARK/RUN function returns the wipers to the PARK Position. The wipers make another sweep every 3 to 4 seconds.

Washer
When you pull the wiper/washer lever towards you, battery voltage is applied to the washer motor and to the wiper relay. The washer motor pumps fluid onto the windshield and the energized wiper relay applies battery voltage to the LO winding of the wiper motor through the wiper switch. The wipers will then run at LO speed until you release the switch.
