Is it moving 'choppy'? It could just need to be the wiper arm assembly rebuilt and lubed, like in my old thread. Martin (mpvc2000) had pictures, but they're gone now.

Basically, you need to pull off the arms, pull off the cowl, undo the three bolts that hold in the whole assembly, wiggle it out, and remove and lubricate the 'pins' that the arms pivot on. I needed a hammer to pound out the pins in mine. I lubricated them with lithium grease, and so far, so good, two years running.
