Glad to be of help ps2cho. I know that you've taken care of the problem now, but you could always install rain sensing wiper controls. I did last year and it is the best mod i have done to my car. I no longer have to fiddle with the wiper, it great on rainy days were the volume of rain keeps changing and your forced to keep changing the wiper setting. It was also very easy to install, only four wires to connect if i recall. I got mine on ebay for like $12 but here is the website of the company, http://www.raintracker.com/.
