System Outline

When the ignition SW is turned on and the glass hatch is closed, current flows through the WASHER fuse to TERMINAL 2 of the rear washer motor, and current also flows through the RR WIPER fuse to the 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 the ignition SW is turned on, the glass hatch is closed and the rear wiper SW is turned to the HI position, current flows through TERMINAL 3 of the rear wiper relay then out TERMINAL 6 to TERMINAL 2 of the rear wiper SW and out TERMINAL 5 to GROUND. As a result, the rear wiper relay operates, and current flows through TERMINAL 3 of the rear wiper relay, out TERMINAL 4 to TERMINAL 3 of the junction SW to the 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, the glass hatch is closed and the rear wiper SW is turned to the LO position, current flows through TERMINAL 3 of the rear wiper relay, out TERMINAL 2 to TERMINAL 1 of the rear wiper SW then out TERMINAL 5 to GROUND. As a result, the intermittent circuit of the relay operates and the rear wiper motor operates.

3. Washer Operation 

   When the ignition SW is turned on, the glass hatch is closed and the rear washer SW is turned to the HI and on+ washer position, and the rear wiper SW is turned further, current flows through the WASHER fuse to TERMINAL 2 of the rear washer motor then out TERMINAL 1 to TERMINAL 3 of the rear washer SW and out TERMINAL 5 to GROUND, so that the rear washer motor rotates and the window washer emits a jet of water. The jet will continue as long as the switch is fully turned.

   When the ignition SW is turned on and the rear wiper and washer SW is in the OFF position, and the washer is turned ON (to wiper OFF side), current flows as above so that the rear washer motor rotates and the window washer emits a jet of water as well as the wipers operating.
