My washers stopped working in the freezing cold and i just guessed it was the fluid that had frozen! Even though i used a winter mix to stop it freezing. It has since got warmer and ive managed to have a look at it and the liquid is not frozen but it still doesnt work and there doesnt seem to be any blockages (checked pipes). Im guessing it may be the motor but dont know where to locate this? Any other ideas and is this a regular problem. My car is a 57 estate.
