Celica Coupe L4-107.5 1762cc 1.8L DOHC (7A-FE) (1995)
Windshield Washer 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 Washer Motor and
TERMINAL 6 of the Front Wiper Motor through the Wiper fuse.
1. LOW SPEED POSITION
With the Wiper SW turned to Low position, current flows from TERMINAL 17 of the Wiper and Washer SW to TERMINAL 7-->
TERMINAL 3 of the Wiper Motor --> Wiper Motor --> TERMINAL 1 Ground, causing the Wiper Motor to run at low speed.
2. HIGH SPEED POSITION
With Wiper SW turned to High position, current flows from TERMINAL 17 of the Wiper and Washer SW to TERMINAL 8 --> TERMINAL 2
of the Wiper Motor --> Wiper Motor --> TERMINAL 1 --> Ground, causing the Wiper Motor to run at High speed.
3. INT POSITION
With the Wiper SW turned to INT position, the relay operates and the current which is connected by relay function flows from TERMINAL 17 of
the Wiper and Washer SW to TERMINAL 2 --> Ground. This operates the intermittent circuit and current flows from TERMINAL 17of the
Wiper and Washer SW --> TERMINAL 7 --> TERMINAL 3of the Wiper Motor --> Wiper Motor --> TERMINAL 1 --> Ground, and
operating 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. MIST POSITION
With the Wiper SW turned to MIST position, current flows from TERMINAL 17 of the Wiper and Washer SW to Front Wiper MIST SW 0-->
TERMINAL 2 --> Ground, and current flows from TERMINAL 17 to TERMINAL 7 --> TERMINAL 3 of the Wiper Motor --> Wiper
Motor --> TERMINAL 1 --> Ground, causing the Wiper Motor to run at low speed.
5. WASHER CONTINUOUS OPERATION
With the Washer SW pushed to ON, current flows from TERMINAL 2of the Washer Motor to TERMINAL 1 --> TERMINAL 11 of the Wiper
and Washer SW --> TERMINAL 2 --> Ground, causing the Washer Motor to run, and the Window Washer emits a water spray. This causes
current to flow to Washer continuous operation circuit in TERMINAL 17 of the Wiper and Washer SW --> TERMINAL 7 --> TERMINAL 3
of the Wiper Motor Wiper Motor --> TERMINAL 1 --> Ground, operating the Wiper.
