Bought a Veccy C a few weeks back and just noticed the 3rd speed setting on the front wipers doesnt seem to work! It hasnt been a problem so far but i can see if being an issue when im on the motorway in heavy down pour.

The lower and middle settings work just fine but when cracking the stalk up to full speed the wipers just park where ever they are positioned at the time?

Any ideas?

Car has 3 months garage guarentee and 12 months AA warranty? Can i fix this myself or does it need to go back to the garage?
