Front Wiper and Washer
SYSTEM OUTLINEWith the ignition SW turned on, the current flows to TERMINAL 17 of the front wiper and washer SW, TERMINAL 2 of the front washer motor and TERMINAL 3 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 to TERMINAL 7 to TERMINAL 5 of the front wiper motor to wiper motor to TERMINAL 1 to GROUND and causes the front wiper motor to run at low speed.
2. HIGH SPEED POSITION
With wiper SW turned to HIGH position, the current flows from TERMINAL 17 of the front wiper and washer SW to TERMINAL 8 to TERMINAL 4 of the front wiper motor to wiper motor to TERMINAL 1 to 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 relay function flows from TERMINAL 17 of the front wiper and washer SW to TERMINAL 2 to GROUND. This flow of current operates the intermittent circuit and the current flows from TERMINAL 17 of the front wiper and washer SW to TERMINAL 7 to TERMINAL 5 of the front wiper motor to wiper motor to TERMINAL 1 to GROUND and operates the wiper.
The intermittent operation is controlled by the charge/discharge function of the condenser installed in the relay and the intermittent time is controlled by a time control SW which changes the charging time of the condenser.
4. WASHER INTERLOCKING OPERATION
With washer SW pulled to on, the current flows from TERMINAL 2 of the front washer motor to TERMINAL 1 to TERMINAL 11 of the front wiper and washer SW to TERMINAL 2 to 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 front wiper and washer SW to TERMINAL 7 to TERMINAL 5 of the front wiper motor to wiper motor to TERMINAL 1 to GROUND and operates the wiper.
