Windshield Wiper/Washer

With the starter switch in ON or START, battery voltage is applied to the windshield wiper/washer switch, windshield wiper motor, and alarm and relay control unit from fuse C-5.

Low Speed
When the windshield wiper switch is moved to LO, battery voltage is applied to the LO winding of the windshield wiper motor and the windshield wipers run at low speed.

Park/Run
When the windshield wiper switch is turned to OFF, fuse C-5 provides battery voltage through the windshield wiper motor, intermittent windshield wiper relay connector plug and the windshield wiper switch to the LO winding of the windshield wiper motor. When the switch on the motor reaches the PARK position, battery voltage from fuse C-5 is removed from the circuit and the windshield wipers stop in the PARK position.

High Speed
When the windshield wiper switch is in HI, battery voltage is applied to the HI winding of the windshield wiper motor and the windshield wipers run at high speed.

Intermittent
When the windshield wiper switch is moved to INT, the windshield wiper switch applies battery voltage to the alarm and relay control unit. The alarm and relay control unit momentarily energizes every 3 to 4 seconds (S models) or a variable time of 2 to 20 seconds (Luxury and Performance models) (depending on intermittent ring position) and applies battery voltage to the LO winding of the windshield wiper motor to move the windshield wipers from the PARK position to the RUN position, then the PARK/RUN function takes over to return the windshield wipers to the PARK position. The windshield wipers make a single sweep approximately every 3 to 4 seconds (S models) or a variable time of 2 to 20 seconds (Luxury and Performance models) (depending on intermittent ring position).

Washer
When the windshield washer switch is depressed, battery voltage is applied to the windshield washer motor and the alarm and relay control unit. The windshield washer motor pumps fluid on the windshield and the alarm and relay control unit energizes and applies battery voltage to the LO winding of the windshield wiper motor through the windshield wiper switch. The wipers run at LO speed until the switch is released.
