I have a 2013 Cadillac ATS. I had to open up the instrument panel fuse box and take out the fuse marked "Display". That finally got it to turn off. However, it's only a temporary fix, since when I put the fuse back in it turned on again. For now I plan to leave it out while my car is off and jimmy rig it with some tape so I can pull it out at any time without pliers/tweezers.
Anyone have any ideas for a more permanent fix? I tried pulling out my RAP relay fuse, but I didn't immediately see any issues with it, and the display was still on when I took it out.
