We have realized that when going reverse polarity the wiper motor is somehow now grounding through the rod that is connected to the shaft of wiper motor. My partner knows more about power situation than I do and that is the issue we are having now. Here is a picture of the possible problem. We used rubber grommets and other stuff as you can see on the wiper motor with the holes and else across the C bar. Now I think the issue is the shaft and the rod somehow. When we took the nut off the wiper motor shaft and let it spin freely with the code, when I would turn left to reverse polarity he saw some sparks he said and then the fuse blew. That is our problem it seems now, anyone dealt with this type of motor before and recommend anything for a possible solution? What we think now is where the bolt is for the rods, to put a rubber grommet inside the rod hole(that the bolt current goes through at the top) that connects the wiper motor and then put the bolt back through. The wiper motor is being controlled by a High power motor driver 18v15.
