Rear Wiper and Washer

When the ignition SW is turned ON, current flows to TERMINAL 2 of the rear washer motor, TERMINAL 3 of the rear wiper relay and TERMINAL 1of the rear wiper motor 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 3 of the rear wiper relay flows to TERMINAL 6 of the relay to TERMINAL 10 of the rear wiper and washer SW to TERMINAL 2 to GROUND. Thus, the relay coil is activated and the current to TERMINAL 3 of the relay flows to TERMINAL 4 to TERMINAL 3 of the rear wiper motor to motor to GROUND and causes the motor to operate the wiper.

2. REAR WIPER INTERMITTENT OPERATION
With the ignition SW turned ON and rear wiper and washer SW turned to INT position, the current flowing to TERMINAL 3 of the rear wiper relay flows to TERMINAL 2 of the relay to TERMINAL 13 of the rear wiper and washer SW to TERMINAL 2 to 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 charge/discharge function 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 switch is turned further, the current flowing to TERMINAL 2 of the rear washer motor flows to TERMINAL 1 of the motor to TERMINAL 12 of the rear wiper and washer SW to TERMINAL 2 to GROUND, so that the washer motor rotates and the window washer emits a water spray, only while the switch is fully turned.

When the wiper switch is OFF and then turned to washer ON (Wiper OFF side) only the washer operates.
