System Outline

With the ignition SW turned on, the current flows to TERMINAL (A) 2 of the wiper and washer SW and TERMINAL 2 of the front wiper motor through the FR WIP fuse. The current flows to TERMINAL 1 of the washer motor through the WASHER fuse.

1. Low Speed Position 

   With the wiper and washer SW turned to LO position, the current flows from TERMINAL (A) 2 of the wiper and washer SW to TERMINAL (A) 3 to TERMINAL 1 of the front wiper motor to TERMINAL 5 to GROUND and causes the front wiper motor to run at low speed.

2. High Speed Position 

   With the wiper and washer SW turned to HI position, the current flows from TERMINAL (A) 2 of the wiper and washer SW to TERMINAL (A) 4 to TERMINAL 4 of the front wiper motor to TERMINAL 5 to GROUND and causes the front wiper motor to run at high speed.

3. INT Position 

   With the wiper and washer SW turned to INT position, the wiper relay operates and current flows from TERMINAL (A) 2 of the wiper and washer SW to TERMINAL (B) 2 to GROUND. This activates the intermittent circuit and the current flows from TERMINAL (A) 2 of the wiper and washer SW to TERMINAL (A) 3 to TERMINAL 1 of the front wiper motor to TERMINAL 5 to GROUND and the wiper operates. Intermittent operation is controlled by a condenser charge and discharge function in the relay.

4. Washer Continuous Operation 

   With the wiper and washer SW pulled to WASHER position (Washer SW ON position), the current flows from the WASHER fuse to TERMINAL 1 of the washer motor to TERMINAL 2 to TERMINAL (B) 3 of the wiper and washer SW to TERMINAL (B) 2 to GROUND and causes the washer motor to run and the window washer to spray. Simultaneously, current flows from the WIP fuse to TERMINAL (A) 2 of the wiper and washer SW to TERMINAL (A) 3 to TERMINAL 1 of the front wiper motor to TERMINAL 5 to GROUND, causing the wiper to function.
