It could be the ground wire, the brake light switch, a damaged wire or connector or the turn signal switch.
Check the bulbs - they are doubloe filamented with the smaller being for brake/turn signals Check the fuses
Try replacing the hazard flasher. If that does not work, double-check to see that you have the proper bulbs and fuses installed for the brake lamp circuit.
I had this same problem. If the bulbs and the fuses are good its most likely the brake switch. Its a plunger like switch on the brake pedal. Its usually the only thing on the brake pedal. Its pretty easy and cheap to change. I would start there.
Next step would be to check the fuses
If the fuses and bulbs are okay I would blame the signal switch assembly. They call it a multi-function switch these days.
The brake lights are a separate circuit from the tail lights. If the bulbs and fuse checks okay, I would suspect the brake light switch is at fault.
If all the bulbs are good then it may be a blown fuse or a defective or mis-adjusted brake light switch.
If you are referring to the brake lights it is probably a bad brake light switch. Your vehicle may also have daytime running lights which would be on without the parking lights.
fuse, bulbs
ya its called go to a mechanic you idiot
First, check all fuses. Then see if you are getting power to the bulbs. Then the next possibility would be the turn signal switch.
Console lights and brake lighting are on different circuits (Fused seperately). Check the following: bulbs, bases, corroded connections, poor ground, blown fuses, faulty light switch.
