high mount 3rd brake light

[Ilikemy3s]

I have an 05' SWB TB .. the high mount 3rd brake light stopped working and I am not sure which fuse to check. Reason I think it might be a fuse is that the bully bar trailer step that also has a brake light built in also is not working. I did check the trailer plug connection. All other lights work as they should. I did google which fuse it should be, but the designation on the fuse box cover does not match what the google answer gave me. Any suggestions would be appriciated.

The fuse is likely labeled "VEH CHMSL"

Fuse 16 under rear seat.
