How many miles / kms? Because of you are under 1 yr and a certain mileage I think it can be changed under the "Adjustments" warranty.
I am not sure, but if you complain that it is crap, then they may change it out. FWIW, I am still running on my OE rear (and front) wipers since I got the van in Dec of 2008, and we get lots of snow, mud and road crap up here.
