2011 Diplomat brake light help

[alwilsey]

Just bought a used 2011 Diplomat. Coming home the chase car said I did not have any brake lights. I looked in the manual and found the fuse and relay panel under driver side window. Changed what I think is a relay with a spare one and no change. I don't see a fuse for it. Any help would be a blessing. Thanks

Welcome to the forum!
If you are fairly handy with a volt meter, you might begin by chasing voltage. Starting at the "hot" side of the switch, at your brake pedal, will tell you if you even have voltage avaliable.
If you do, mash the pedal, check on the other side if the switch, if you find voltage, the switch is likley good. Move to the back of the bus, check at each light socket, you might find a bad ground at this point, and all that requires is a scraping or sanding, at worse, a new wire.
If you are not comfortable with a volt meter, a test light will work fine, maybe better!
Let us know...and again..
WELCOME

I got through to tech support at Monaco and after some trial and error they led me in the right direction. It turns out that the fuses for the brake lights are located in the front left compartment but they are not labeled in the book or on the door of the compartment. After using a cheat sheet as they call it at tech support I was led to F81 (the bad one) and F82. On to the next problem and thanks to the responders to my initial question.
