Flashers not working. Brake lights not working. Turn signals weren't either but found and replaced fuse so those work but can't locate any fuses or relays for the others and manual doesn't list them.RV is 2005 class A Gulfsteam Sunseeker with 8.1 Chevy Workhorse chassis.

Time to visit a Chevy dealer if you can’t find it.

Just an idle thought, but I'll toss it out since you haven't had a specific reply yet.The coach builder often uses the "Trailer" wiring, fuses, etc. when they put an RV body onto a bare chassis. This could lead you to a different group of fuses, maybe even in a different fuse panel. Have you tested for power at your Trailer Tow socket? Probably powered from same group of fuses as rear turn signals, brake and marker lights. And possibly a common connection point down on the chassis.

Under the hood. Dead center, eye level for my 6' person, is a black box NO LABELSLatches on each side of the box.. Fuse layout on inside of cover

Found that box and a fuse that says brake and it was fine. Did not find one labeled flasher but did look at several other fuses there and they all seem to be in good order. Still no brake or flasher lights.

The other fuse (There are two fuses One for TURN and one for Brake/4-ways) is on the I/P panel near the driver's left foot.
