Friends, I have been through all of the wiper threads and I am still stumped. I rebuilt the wiper switch and I have checked the wires, but I don't get anything. The previous owner said that he was able to run the motor hooking it directly to a 12v battery. The only thing I keep reading about is a white ground wire which I can't seem to find. The power does look very low at the motor harness connection though, Any insight is greatly appreciated.
