Ok buy a test light then remove the tails and bulbs have someone press the brake and use the test light to see if there is power, if there is get new bulbs if there isn't start hunting for a blown fuse, if the fuse is fine (check it with the test light), then check along the wire till you find a fault (broken wire, chatting, short, etc) if there's no power at all and the fuse refuses to light up the test light, then check out the switch or possibly the flasher relay. Hell you could try jumping the light using a wire straight from the battery to avoid hunting down the wire just to determine the line is unbroken.
Yeah, basic troubleshooting. My last post was sarcasm. Black_demon had said "find and push the red button"... That resets the brake lights.
Besides, killjoy, you explained how to troubleshoot, but how do you RESET them?
