Low Speed

With the ignition switch in RUN or START battery voltage is applied to the windshield wiper motor through fuse 6. When you turn the wiper switch to LOW, the low speed winding of the motor is grounded through the low contact of the wiper switch, and the wipers run at low speed.


Park/Off

When the wiper switch is turned 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 park.


High Speed

When the wiper switch is in HIGH, the high speed windings of the windshield wiper motor are grounded through the high contact of the wiper switch, and the wipers run at high speed.


Intermittent


When the wiper switch is moved to INT, battery voltage is applied through the GRN wire to the integrated control unit, which intermittently grounds the coil of the intermittent wiper relay. The relay, in turn, provides ground to the low speed windings of the wiper motor, and the wipers make a single sweep. The cycle repeats about every five seconds.


Mist

When you pull the wiper switch lever down to MIST and release it, the high speed winding of the wiper motor is grounded through the mist contact in the wiper switch, and the wipers make one sweep at high speed and return to the PARK position.


Washer

When you pull the wiper switch lever towards you, battery voltage is applied to the washer motor, and the wash input of the integrated control unit through the BLU/YEL wire (except DX models). The integrated control unit grounds the wiper motor low speed winding (see low speed, and intermittent operation). The motor runs for as long as you hold the lever back. Once you release the lever, the wipers will continue their sweep until they reach the PARK position.
