3 things come to mind...Fuse, Bad Bulbs, Brake Light Switch. Whip out the volt meter and test it at the bulb socket for 12 volts when your buddy pushes the brake. Check the fuse, bad bulbs first.
Blown fuse
I had that issue with my Cavalier and it turned out to be a fuel pump problem. I would check with your local mechanic.
there is a fuse on the fire wall that looks like a plug there is a consistent power connection above it
fix it

blown engine, out of gas janitorial duties.
Check the operation and alignment of the stop light switch
sounds like the water pump is gone. that may be where the leak is coming from. could also be the cap for the coolant res. or thermostat
You can't turn on the ETS manually. It only comes on when the computer senses wheel spin. You should notice it coming on during a heavy rain or when accelerating quickly from a dead stop.
Bulbs burned out or fuse and or relay popped
