Re: New Wiper blowing fuses???
The OEM wiper motor has power applied directly to the motor - yellow wire I believe. The switch applies ground to the two blue wires. The switch body is grounded.
I don't know if this is typical of all wiper motors. Any chance you got one with a grounded motor and the speed is changed by apply voltage through the switch.
Is the fuse blowing the moment you insert it, or only after actuating the switch?
