System Outline

When the ignition SW is turned on, current flows to TERMINAL 17 of the front wiper and washer SW, TERMINAL 2 of the front wiper and washer motor through the WIPER fuse and TERMINAL 1 of the windshield wiper motor through the WASHER fuse.

1. Low Speed Position 

   When the front wiper and washer SW is turned to the LO position, current flows in TERMINAL 17 of the front wiper and washer SW, out TERMINAL 7 to TERMINAL 1 of the front wiper motor, and finally out TERMINAL 5 to GROUND and causes the front wiper motor to run at low speed.

2. High Speed Position 

   When the front wiper and washer SW is turned to the HI position, current flows in TERMINAL 17 of the front wiper and washer SW, out TERMINAL 8 to TERMINAL 4 of the front wiper motor, and finally out TERMINAL 5 to GROUND and causes the front wiper motor to run at high speed.

3. INT Position 

   When the wiper and washer SW is turned to the INT position, the wiper relay operates and current flows from TERMINAL 17 of the front wiper and washer SW and out TERMINAL 2 to GROUND. This activates the intermittent circuit and current flows from TERMINAL 17 of the front wiper and washer SW then out TERMINAL 7 to TERMINAL 1 of the front wiper motor and out TERMINAL 5 to GROUND and the wiper operates. Intermittent operation is controlled by a condenser charge and discharge function in the relay.

4. Washer Interlocking Operation 

   When the front wiper and washer SW is pulled to the washer position (Washer SW ON position), current flows from the WSH fuse to TERMINAL 1 of the front washer motor and out TERMINAL 2 to TERMINAL 11 of the front wiper and washer SW then out TERMINAL 2 to GROUND and causes the front washer motor to run and the window washer to spray. Simultaneously, current flows from the WIP fuse to TERMINAL 17 of the front wiper and washer SW and out TERMINAL 7 to TERMINAL 1 of the front wiper motor then out TERMINAL 5 to GROUND, causing the wiper to function.
