Rear Wiper and Washer

When the Ignition SW is turned ON, current flows to TERMINAL 2 of the Washer Motor, TERMINAL 1 of the Rear Wiper Motor and Relay Through the WIPER fuse

1. REAR WIPER NORMAL OPERATION
With the Ignition SW turned ON and Rear Wiper and Washer SW turned ON, the current flowing to TERMINAL 1 of the Rear Wiper Relay flows to TERMINAL 3 of the Relay --> TERMINAL 1 of the Rear Wiper and Washer SW --> TERMINAL 16 --> to GROUND. Thus, the Relay Coil is activated and the current to TERMINAL 1 of the Relay flows to TERMINAL LM --> TERMINAL LM of the Rear Wiper Motor --> Motor --> to GROUND and causes the Motor to operate the Wiper.

2. REAR WIPER INTERMITTENT OPERATION
When the Ignition SW is ON and the Rear Wiper and Washer SW is turned to INT position, current flowing to TERMINAL 1 of the Rear Wiper Motor and Relay Flows to TERMINAL 2 of the Relay --> TERMINAL 10 of the Rear Wiper and Washer SW --> TERMINAL 16 --> GROUND.

This causes the Motor to operate (The Point Changes) and the Intermittent circuit of the Relay Operates. Intermittent operation of the circuit is controlled by the charging and Discharging of the condenser installed inside the Relay.

3. WASHER OPERATION
With the Ignition SW turned ON and the Rear Wiper and Washer SW turned to ON position, when the Wiper SW is turned further, the current flowing to TERMINAL 2 of the Washer Motor flows to TERMINAL 3 of the Motor --> TERMINAL 2 of the Rear Wiper and Washer SW --> TERMINAL 16 --> to GROUND, so that the Washer Motor Rotates and the Window Washer ejects the Spray, only while the Switch is fully turned.

When the Wiper SW is OFF and then turned to Washer ON (Wiper OFFSide), only the Washer operates.
