I've got a 1979 1303 "vert" equipped with a wisch-wasch screen scrappers. The relay that controls the interval wisch is gone crazy. The VW number on the relay is 111 955 531. I was wondering if it's possible to replace the original relay with one of a VW rabbit because the relay number for this car has the VW number 1HM 955 531 en it's a lot cheaper to come by. Help welcome.
