These, I'm told, are a comon fault with Fiestas, inthat they don't work! - P' reg, 96, not sure what Mk.... The handles (drivers side and passenger side, front - rears work fine) operate by pushing a thin metal bar downwards, this bar is inside a plastic gromit, which is clipped into a flat metal plate which does the buisness of opening and closing the mechanism - these plastic inserts wear away, they are only about an inch long and half an inch wide.
any ideas where they might be available?
