Car is E300D 1995...someone please tell me where the buzzer is located and how to shut the xxxxing thing off.
It buzzes every time I step on the brake AND I CAN'T TAKE IT ANYMORE!!!

That sounds like the big relay behind the fuses... If the #5? fuse is blown, that relay can buzz. Or is it the green top relay?

Check all fuses and then check the relays, one has a flat blade fuse in it. Can't remember which one.

Once you open it up, get a helper to push the brakes for you. I bet you figure it out in just a few minutes.

Thanks, it sounds/feels as if it is coming from area by my left knee, but definitely inside the car not in engine bay. Guess I'll have to pull the panel below the steering wheel. I was hoping there was another way to disable it.
