System Outline

When the ignition SW is turned on, current flows to TERMINAL 17 of the 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 

   With the wiper and washer SW is turned to the LO position, current flows from TERMINAL 17 of the wiper and washer SW then out TERMINAL 7 to TERMINAL 1 of the front wiper motor and out TERMINAL 5 to GROUND causing the front wiper motor to run at low speed.

2. High Speed Position 

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

3. INT Position 

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

4. Washer Interlocking Operation 

   With the wiper and washer SW turned 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 wiper and washer SW and out TERMINAL 2 to GROUND causing 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 wiper and washer SW and out TERMINAL 7 to TERMINAL 1 of the front wiper motor then out TERMINAL 5 to GROUND, causing the wipers to function.
