My fiat punto screen washers appear to have stopped working. At first I thought the water bottle was empty as the motor was heard but no water came out, but I didnt need much water to fill it up so that wasnt the problem. The washer motor was making a noise when i pulled or puched the lever but only a very slow trickle came out of the front and nothing at the back. I checked for blockages with a needle and also made sure the pipes were connected under the bonnet. I tried again and after a while the motor noise also stopped as well. I noticed the fuse is the same one as the wipers and they still work so it cant be a dead fuse. Can anyone suggest what I can do. My punto is an '02 1.2 Active. I've just had a new battery put in but its only done 42000 miles so isnt worn out. Thanks
