Hi everyone

This is the first time I've posted on this site and the first time that I've even been onto it, I've got an A class and am having a prob with my windscreen wipers. They seem to have gotten out of sync with one another all of a sudden and keep breaking, I thought it was just a freak accident at first but 30 secs after paying for a new wiper blade the same thing happened.

Has anyone got any ideas as to how I can sort it out or reset it myself without having to take it to a garage?? I'm really trying not to spend anymore money on it.

Thanks!
