RAV4 4-Door 4WD L4-2.0L (3S-FE) (1997)
Wiper Motor: Description and Operation
Front Wiper and Washer
With the Ignition SW turned ON, current flows to TERMINAL 17 of the Front Wiper and Washer SW, TERMINAL 2 of the Front Washer Motor and
TERMINAL 6 of the Front Wiper Motor through the WIPER fuse.
1. LOW SPEED POSITION
With Wiper SW turned to LOW position, the current flows from TERMINAL 17 of the Front Wiper and Washer SW --> TERMINAL 7 -->
TERMINAL 3 of the Front Wiper Motor --> TERMINAL 1 --> GROUND, causes the Front Wiper Motor to run at low speed.
2. HIGH SPEED POSITION
With the Wiper SW turned to HIGH position, the current flows from TERMINAL 17 of the Front Wiper and Washer SW --> TERMINAL 8 -->
TERMINAL 2 of the Front Wiper Motor --> TERMINAL 1 --> GROUND, and causes the Front Wiper Motor to run at high speed.
3. INT POSITION
With Wiper SW turned to INT position, the Relay operates and the current which is connected by the relay function flows from TERMINAL 17
of the Front Wiper and Washer SW --> TERMINAL 2 --> GROUND. This flow of the current operates the intermittent circuit, and current flows
from TERMINAL 17 of the Wiper and Front Washer SW --> TERMINAL 7 --> TERMINAL 3 of the Front Wiper Motor --> Wiper Motor -->
TERMINAL 1 --> GROUND and operates the Wiper.
The Intermittent operation is controlled by a condenser's charged and discharged function installed in the relay and the intermittent time is
controlled by a time control SW to change the charging time of the condenser.
4. WASHER CONTINUOUS OPERATION
With Washer SW turned to ON, current flows from TERMINAL 2 of the Front Washer Motor --> TERMINAL 1 --> TERMINAL 11 of the
Front Wiper and Washer SW --> TERMINAL 2 --> GROUND, and causes to the Front Washer Motor to run and the Window Washer emits a
water spray. This causes the current to flow to Washer continuous operation circuit in TERMINAL 17 of the Wiper and Washer SW -->
TERMINAL 7 --> TERMINAL 3 of the Front Wiper Motor --> Wiper Motor--> TERMINAL 1 --> GROUND and operates the Wiper.
