I posted a thread about this and thought that the problem was sorted but it isn't 
I turned my wipers on when there was heavy snow the other week (stupid me) and ever since, the wipers aren't working. I've had a look and the bolts that hold the wiper arms on are loose so the wipers don't work. I'm not sure if the motor part is bent but can't check as I have no idea how to remove the cover that sits on top of them (hope this makes sense).
I was wondering if anyone would have a clue as to how much this will cost to fix it?
