Rear Wiper and Washer
System OutlineWhen the ignition SW is turned on and glass hatch is closed, the current flows through the WASHER fuse to TERMINAL 2 of the rear washer motor, the current flows through the RR WIPER fuse to IG relay (Point side) to TERMINAL 7 of the junction SW and TERMINAL 3 of the rear wiper relay.
1. Rear Wiper Normal Operation
When this ignition SW is turned on, glass hatch is closed and rear wiper SW turned to ON position, the current flows through the TERMINAL 3 of the rear wiper relay to TERMINAL 6 to TERMINAL 2 of the rear wiper SW to TERMINAL 5 to GROUND. As a result, the rear wiper relay is operated, and the current flows through the TERMINAL 3 of the rear wiper relay to TERMINAL 4 to TERMINAL 3 of the junction SW to rear wiper motor to TERMINAL 1 of the junction SW to GROUND, causing the motor to operate the rear wiper.
2. Rear Wiper Intermittent Operation
When the ignition SW is turned on, glass hatch is closed and rear wiper SW turned to INT position, the current flows through the TERMINAL 3 of the rear wiper relay to TERMINAL 2 to TERMINAL 1 of the rear wiper SW to TERMINAL 5 to GROUND.
As a result, the intermittent circuit of the relay operates and the rear wiper motor operates.
3. Washer Operation
With the ignition SW is turned on, glass hatch is closed and rear washer SW turned to ON and washer position, when the rear wiper SW is turned further, the current flows through the WASHER fuse to TERMINAL 2 of the rear washer motor to TERMINAL 1 to TERMINAL 3 of the rear washer SW to TERMINAL 5 to GROUND, so that the rear washer motor rotates and the window washer emits a water, only while the switch is fully turned.
When the rear wiper SW is off and then turned washer on (Wiper off side), the rear wiper SW is on and then turned to washer on (Wiper on side), only the washer operates.
