System Outline

When the ignition SW is turned on, current flows to TERMINAL 8 of the front wiper and washer SW, TERMINAL 2 of the front wiper motor through the WIPER fuse and TERMINAL 2 of the windshield wiper motor through the WASHER fuse.

1. Low Speed Position 

   When the front wiper SW is turned to the LO position, current flows in TERMINAL 8 of the front wiper and washer SW, out TERMINAL 7 to TERMINAL 1 of the front wiper motor, and finally out TERMINAL 5 to GROUND and causes the front wiper motor to run at low speed.

2. High Speed Position 

   When the front wiper SW is turned to the HI position, current flows in TERMINAL 8 of the front wiper and washer SW, out TERMINAL 9 to TERMINAL 4 of the front wiper motor, and finally out TERMINAL 5 to GROUND and causes the front wiper motor to run at high speed.

3. INT Position 

   When the front wiper SW is turned to the INT position, the wiper relay activates and current flows in TERMINAL 8 of the front wiper and washer SW then out TERMINAL 5 to GROUND. This activates the intermittent circuit and current flows in TERMINAL 8 of the front wiper and washer SW then out TERMINAL 7 to TERMINAL 1 of the front wiper motor and finally out TERMINAL 5 to GROUND activating the wipers.

   The intermittent operation is controlled by the charge/discharge function of the condenser installed in the relay, and the intermittent time is controlled by a time control SW (w/ intermittent volume SW) to change the charging time of the condenser.

4. Mist Position 

   When the front wiper SW is turned to the MIST position, the current flows in TERMINAL (B) 2 of the front wiper and washer SW, out TERMINAL 7 to TERMINAL 1 of the front wiper motor then out TERMINAL 5 to GROUND and causes the front wiper motor to run at low speed.

5. Washer Continuous Operation 

   When the front washer SW is turned on, current flows from TERMINAL 2 of the front washer motor then out TERMINAL 1 to TERMINAL 4 of the front wiper and washer SW and out TERMINAL 5 to GROUND, and causes to the washer motor to run, and the window washer jet operates. This causes current to flow to the washer continuous operation circuit in TERMINAL 8 of the front wiper and washer SW then out TERMINAL 7 to TERMINAL 1 of the front wiper motor and out TERMINAL 5 to GROUND and the washer operates continuously.
