INT Position

When the wiper and washer SW is turned to the INT position, the wiper relay operates and current flows from TERMINAL (B) 2 of the wiper and washer SW then out TERMINAL (A) 2 to GROUND. This activates the intermittent circuit and current flows from 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 and then the wiper operates. The intermittent operation is controlled by the condenser charge and discharge function in the relay.
