System Outline

When the ignition SW is turned on, current flows to TERMINAL 17 of the front wiper and washer SW, TERMINAL 1 of the washer motor and TERMINAL 2 of the front wiper motor through the FR WIP-WSH fuse.

1. Low Speed Position

   If the front wiper and washer SW is turned to the LO position, 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 causes the front wiper motor to run at low speed.

2. High Speed Position

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

3. INT Position

   If the front 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. The intermittent operation is controlled by a condenser charge and discharge function in the relay.

4. Washer Interlocking Operation

   With the front wiper and washer SW pulled to the washer position (Washer SW ON position), current flows from the FR WIP-WSH fuse to TERMINAL 1 of the washer motor then out TERMINAL 2 to TERMINAL 11 of the front wiper and washer SW and out TERMINAL 2 to GROUND and causes the washer motor to run and the window washer to spray. Simultaneously, current flows from the FR WIP-WSH 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.
