Wipers Stopped Working

As per thread title, the wipers on my 200 have suddenly stopped working and they are quite 'floppy' (i.e. can move them easily with my hand). What's the first thing to check on this? I've read it could be the motor, a relay or a 20A fuse. Fuse should be easy to check and eliminate but not sure about the relay or the wiper motor, or if it could be something else?

Thanks,
Dave.
 
Nut may have come loose on the motor, or the mechanism may have snapped/come loose, mine stopped as the pins seized, had to strip it down though to find out the problen
 
Turned out to be a nice easy fix - the nut fastening the arm to the wiper motor had indeed come undone. Sorted this out today an back in business.
