Wiper and Washer With INT Time SW

System Outline

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

1. Low Speed Position
With the wiper and washer SW turned to LO position, the current flows from TERMINAL (A) 2 of the combination SW to TERMINAL (A) 3 to TERMINAL 1 of the windshield wiper motor to TERMINAL 5 to GROUND and causes the windshield 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 combination SW to TERMINAL (A) 4 to TERMINAL 4 of the windshield wiper motor to TERMINAL 5 to GROUND and causes the windshield 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 combination SW to TERMINAL (B) 2 to GROUND. This activates the intermittent circuit and the current flows from TERMINAL (A) 2 of the combination SW to TERMINAL (A) 3 to TERMINAL 1 of the windshield 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 on position (Washer SW ON position), the current flows from the WSH fuse to TERMINAL 1 of the windshield washer motor to TERMINAL 2 to TERMINAL (B) 3 of the combination SW to TERMINAL (B) 2 to GROUND and causes the windshield washer motor to run and the window washer to spray. Simultaneously, current flows from the WIP fuse to TERMINAL (A) 2 of the combination SW to TERMINAL (A) 3 to TERMINAL 1 of the windshield wiper motor to TERMINAL 5 to GROUND, causing the wiper to function.
