Can someone explain the electrical system as it relates to the wipers and washers on a 67 GS? I have all the components - switch, wiper motor with a washer motor and all new wiring. The wiper motor has 3 terminals - light blue - low speed, black - high speed & yellow - constant power. The washer motor has 2 terminals - dark blue - switch & yellow - constant power. The switch has 3 terminals - light blue - wiper low, black - wiper high & dark blue - washer control. How does this all function together? It is currently non-functional. I have power to the yellow when I turn on the ignition. But when I turn on the switch it blows a 25A fuse. Help needed. Thanks
