No good news. I just read my owners book and there is 3 lines dedicated to heated grips. They say nothing about fuses for the grips just turn on and off.
I went to victorys web page and looked up a 2015 vision and still nothing about fuses.
So look in the left hand fuse box for a bad one. Might be the same as horn fuse. If you can't find a bad fuse your going to have to pull the dash panel. There is 3 wires going to switch and maybe the center one that feeds the power slipped off. Take plenty of photos to get the right wires back in the right spot.
IMPORTIN there is a small allen screw in glove box that helps hold dash down.
