If Wolverine were blinded, he'd mostly rely on his sense of smell and hearing but no matter how good these senses are, Daredevil has radar sense which is a hell of a lot better.
That being said, I have to say that the fight still goes to Wolverine seeing as there's no way Daredevil can hurt Logan without the wound being healed right away. Wolverine can basically just stand there and take everything Matt can throw at him but once the Man without fear closes in, all it takes is one slash from those pigstickers and Matt's down for the count.
