A while back, I had an issue w/my 04 330cic where the wiper blades wouldn't reset all the way down after completing a full wiping cycle.
I did a bunch of searches on this and other boards, and found references to replacement of the wiper relay. It was a really easy switch - no special tools required, and a simple plug-in replacement under the hood.
The part was somewhere in the < $15 range as well, got if from the dealer w/my CCA discount.
