Washer Interlocking Operation

When the 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 (A) 3 of the wiper and washer SW and out TERMINAL (A) 2 to GROUND and runs the washer motor and the window washer to spray. Simultaneously, current flows from the WIP fuse to TERMINAL (B) 2 of the wiper and washer SW then out TERMINAL (B) 3 to TERMINAL 5 of the front wiper motor and out TERMINAL 4 to GROUND, which activates the wiper.
