I hear your cries for help, last hear my blower motor went and about a month later, my wiper linkage seized, or fell apart. I was able to do the blower motor myself, after much difficulty, but left the wiper linkage to a BMW mechanic (not the dealer). Some money is better spent leaving it to a professional. My 2 cents. Since then my wiper system feels like it's off a new car.
