My buddy had the same thing, forget what fixed it, I think the turn signal arm assembly was replaced. Also it could have been the clock spring??? I think that is what it was called, but almost 100% on the arm bieng kaput. Try wiggling the harness that attaches it before buying a new one, 80 bucks, making sure it's not loose. It's a bit of a biatch to get at so be gentle.
