I had same issue. It's the fuse box it's self! Under rear seat there is a TSB about it. Easiest fix is replace fuse box. I took mine apart and fixed it. But I don't recommend doing it it was a PIA to do. You can get by for a little while by twisting the legs of the relay and fuse just a little , to help make a good connection. But it will only last 75-100miles before it blows or just loses connection again. Good luck
