my wipers have given up!!!

my wipers stopped working completely last night,
 the motor is still wurring away, but nothing is moving up front!!!
 havent had a chance to have a look yet, due to being dark last night and having to work 2day (how inconsiderate!)
 
 gunna have a look when i get home 2nite, so if anyone has had this happen before and would like to pass on any tips of what i should be looking for then that would be groovy.
cheers!

are the spindles still turning? if yes, then the arms have come loose. if not then it's probably a linkage problem.

If you need a replacement mech and/or motor gimme a shout.

not entirely sure whats going on with them at the mo,
 as i say the motor sounds as if its turning, but no movement of the blades, i cant hear any banging or clunking from the linkage flying about either!!!! i will have a proper look when i get home.
 cheers for your quick replies though,
will keep you posted.
cheers

sorted, easy peasy!
 the culprit was a loose 10mm nut sitting on top of the motor. so the linkage wasnt rotating at all!
 just tightened her up and hey presto! i can see again.

cheers
