yes I have the washer control button on the leftside panel near the dash. Also the holes in the screen for the nozles but nothing is there. It means that the previous owner took it out.
I read that the system was not a very good one, but just for perfectionism to make it original. But I will check for a replacement that works better. Have to see if the operating button inside on the left panel was electrical powered or vacuum hoses run from it. I can, just for the sake of having a washing system, get a working electrical system from an old modern car and when I will found an original by chance I might buy it.
thanks and regards
