Ha ha, thanks for the 1000 points. I don't really understand the feedback thing either. And I hope that your car gets fixed soon. As I'm sure you know, having no wipers on a rainy night isn't very safe.

I also hope that my advice helps you and that checking the wires wont be a waste of time, since I'm not a mechanic or anything. But I do remember reading somewhere about a problem like yours with blowing fuses on some other website, and someone suggested that the wires may be corroded, and the person replied that they were right, so I'm thinking you have the same problem.
