ford focus - wipers stopped working. You can hear noise when turned on - but the wipers dont move. Also if you pull on the wipers - they move freely and in tandem. I have not pulled anything apart yet - wasn't sure if the motor needed replacement or if the linkage was broken. Happened during wet heavy snow storm. Any thoughts? Before I buy any parts - didn't want to get what i don't need - if possible.

sometimes the linkeage bolts get loose, if not that, linkeage is broken
