i have the same issue, but it has been going on for quite a long time... the rear wiper kept wiping the glass after i washed it and i think the only way to stop it, was to switch off the car...
then it didnt do this joke for quite a while, but now all of the wipers keep wiping and when i wash the front window, it blows the fuse... when i wash the rear window, it even blows water on the rear glass and wipes it normally, but at the same time, all of the wipers still keep wiping... and again.. when i want to wash the front windshield, it blows the fuse again...
it could be the same switch on the steering column then? -_- (it started to blow the fuse with a hot weather and an empty washing tank... should probably keep the tank always full then?)
