I own a 2018 Tahoe Premier with the 6.2L RST package. I cracked my third brake light and water got in and shorted it out. I replaced the light fixture and the wire/wiper fluid tube harness but it still isn’t working. Is there a fuse for the third brake light? I couldn’t find it in the owners manual. Any help is very much appreciated.

Bump. Anyone have any insight on this?
if it is not shown in the owners manual then the gm upfitter guide usually shows what other things are attached to certain fuses.
it's probably not something that a lot of people are going to have committed to memory.
if you can't find it in the upfitter guide then go old school and start testing fuses easy to do by just touching the outer contacts with meter probes.

Thank you for the information! I’ll look into the up fitters guide.
