Rear Wiper and Washer

When the ignition SW is turned ON, current flows to TERMINAL 2 of Washer Motor, TERMINAL 4 of Rear Wiper relay and TERMINAL 1 of the Rear Wiper Motor through the Wiper fuse.

1. REAR WIPER NORMAL OPERATION
With the ignition SW turned ON and the Rear Wiper and Washer SW turned ON, the current to TERMINAL 4 of the Rear Wiper relay flows to TERMINAL 6 of the relay --> TERMINAL 1 of the Rear Wiper and Washer SW --> TERMINAL 16 --> GROUND. Thus, the relay coil is activated, and the current to TERMINAL 4 of the relay flows to TERMINAL 1 --> TERMINAL 4 of the Rear Wiper Motor --> Motor --> TERMINAL 2 --> GROUND, causing the Motor to rotate to operate the Wiper.

2. REAR WIPER INTERMITTENT OPERATION
With the ignition SW turned ON and the Rear Wiper and Washer SW turned to INT position, the current to TERMINAL 4 of the Rear Wiper relay flows to TERMINAL 3 of the relay --> TERMINAL 10 of the Wiper SW --> TERMINAL 16 --> GROUND. As a result, the relay is activated, and current flows from TERMINAL 4 of the relay to TERMINAL 1 --> TERMINAL 4 of the Rear Wiper Motor --> Motor --> TERMINAL 2 --> GROUND, causing the Motor to rotate to operate the Wiper. At this time, the contact in the Rear Wiper Motor is closed, and current flows from TERMINAL 1 of the Rear Wiper Motor --> TERMINAL 3 --> TERMINAL 2 of the Rear Wiper relay --> TERMINAL 1 --> TERMINAL 4 of the Rear Wiper Motor --> TERMINAL 2 --> GROUND.
Thus, the intermittent-stop circuit operates, the condenser in the circuit charges and the Wiper continues to operate until reaching at STOP position. After the Wiper stops, current does not flow to the intermittent-stop circuit from TERMINAL 2 of the relay, but the condenser discharges current into the intermittent circuit and the circuit operates until the condenser discharge is done. As a result, this discharge interval becomes the intermittent time.
When the current is discharged completely, the current to TERMINAL 4 of the relay flows to TERMINAL 3 --> TERMINAL 10 of the Rear Wiper and Washer SW --> TERMINAL 16 --> GROUND.
Then, the current through TERMINAL 4 of the relay flows to TERMINAL 1 --> TERMINAL 4 of the Rear Wiper Motor --> Motor --> TERMINAL 2 --> GROUND, causing the Motor to rotate. Through repetition of this process, intermittent operation of the Rear Wiper occurs.

3. WASHER OPERATION
With the ignition SW ON and the Rear Wiper and Washer SW turned strongly (Washer SW ON), current flows from TERMINAL 2 of the Washer Motor --> TERMINAL 3 --> TERMINAL 2 of the Rear Wiper and Washer SW --> TERMINAL 16 --> GROUND so that the Washer Motor rotates and window Washer ejects the spray, only while the Rear Washer SW is turned. When the Rear Wiper SW is OFF, and the Rear Wiper and Washer SW is then turned in the OFF direction, Washer liquid will also spray.
