Did you get this figured out?
Speaking of wiper breaking, I went out to scrape snow/ice on my wife's MINI since it was caked on and she had to leave. This was nighttime so it was dark. Well I apparently really didn't see the passenger side wiper and the thing flew off the car as I scraped it, doh!!! Thankfully there was no damage to the wiper arm and stuff, just broke some plastic off the blade assembly itself. Got a new one and it's good. Expensive to get the real MINI one though, and had to get the pair. Well at least we have the rubber blades saved from the extras and we can slide those in later if needed years down the road.
