no... I would suspect a MAJOR mis-wiring. depending on the vehicle, it could be something in the ECU or printed circuit board.
I would suspect a weak ground connection.
the ground for the rear lights is by the radio aerial inside the rear passanger side wing.
Check for a bad ground
Most likely a fuse or a bad ground.
check the ground wires that are on the radiator support, below the air box, down behind the lt, headlamp.
If the vehicle is equipped with a trailer light plug, the wires for the brake lights and the turn signals have been connected together, which is common, as many trailers do not have separate lights for brakes and turn signals.
check for a loose ground wire
we are having back brakes problems
You have a short, you also may have to check your bulbs i found on one of my blinkers the bulb was faulty, i replaced it and everything was all fine again.
A wire may be cut from the brakes. the turn signal wire is still connected
No brake lights but turn signals work? Turn signal switch brakes route through it.
I would suspect that you've put a 6 volt bulb into a 12 volt vehicle.
