98 Silverado Brake Light Problem

I have a 1998 Silverado Z71. Last week, my brake lights, rear turn signals
and rear hazard lights stopped working. The front lights work as they
should. The fuses are good and the bulbs are good as well (when I turn my
headlights on, the rear lights up). My first thought was that it was the
brake lamp relay in the fuse box under the hood, but I called my local Chevy
dealer and that part doesn't even come up in their computer. My mechanic
thinks it may be my brake light switch. My question is: if my brake light
switch is bad, would this also cause the rear blinkers/hazards to
malfunction? Any other ideas?

Thank you.

i agree with the turn signal switch because on those they call it a
multi function switch and it runs the hazards and turn signals. and
also the brake lights are fed through it. you can usually wiggle your
hazard switch and things will start working
