The fuse is in the fuse box. Fix you don't see it in the fuse box it might be missing. Replace it with the CORRECT amp fuse.
Bottom part of diagram is not in sight ..3 big fuses
I just googled it. It looks like it might be a relay and not a fuse. Go to Google and use the images. It will pull up pictures of your fuse box diagrams.

It’s on the back of the interior fuse box. There’s also a screw that holds it in place connected threw the inside of the glove box
