High mount brake light issues

[Strange1500]

Hi everyone, I’m new to the group! I’ve got a 2015 ram and my high mount brake light isn’t working. I checked the bulbs, they’re all good. I’ve done some online searches and anything I find says chmsl fuse is likely the problem. However I’ve looked at my fuse box over and over as well as the owners manual and neither show a high mount stop light fuse. So I’m a little confused as to what to look for! Any help would be much appreciated, thank you!

Check for power/ground at the bulb. Or just replace the bulb anyway to start. I’ve seen a lot of bulbs that look fine but aren’t.
