A FRIEND OF MINE HAS A MODEL YEAR 2004 PONTIAC G6. RECENTLY HE WAS INVOLVED IN AN ACCIDENT WITH ANOTHER INDIVIDUAL , WHO WAS DRIVING A MODEL YEAR 2006 HONDA CIVIC. MY FRIEND RECEIVED SLIGHT DAMAGES TO THE RIGHT CORNER OF THE REAR BUMPER. MY FRIEND SAYS THAT, SINCE THE ACCIDENT, HIS BRAKE LIGHTS ARE CONTINUALLY ON AND WILL ONLY COME OFF WHEN HE HITS THE BRAKE PEDAL. HE MAINTAINS THAT THE ACCIDENT CAUSED THIS TO HAPPEN. I MAINTAIN THAT, DUE TO MODERN TECHNOLOGY, ONLY THE RIGHT REAR SIDE WOULD BE AFFECTED AND HIS PROBLEM WOULD ONLY BE CAUSED BY SOMETHING ELSE, SUCH AS A BRAKE LIGHT SWITCH. PLEASE ADVISE WHO IS CORRECT. TKS.
I would have to obtain a wiring diagram of the car to be 100% certain. However, tail and brake light circuits are usually tied together at the fuse panel. This means that whatever happens local to one tail light will not affect the other because it is essentially an independent circuit until you get to the fuse panel. It is almost certainly a brake light switch.
