THOSE LIGHTS ARE ON 2 DIFFERENT CIRCUITS. ONE WHITE WIRE COMING OUT OF THE BRAKE LIGHT SWITCH GOES TO THE CENTER BRAKE LIGHT. THE OTHER WHITE WIRE GOES FROM THE BRAKE LIGHT SWITCH TO & THROUGH THE TURN SIGNAL SWITCH SO THE LIGHTS CAN BE USED AS BRAKE LIGHTS OR TURN LIGHTS. THE BRAKE LIGHT SWITCH IS GOOD BECAUSE THE CENTER BRAKE LIGHT IS WORKING. IT IS A BAD WIRE { WHITE } FROM THE BRAKE LIGHT SWITCH TO THE TURN SIGNAL SWITCH OR A BAD TURN SIGNAL SWITCH.

CHECK BRAKE LIGHT SWITCH TO SEE IF ITS TOUCHING THE BRAKE PEDAL.IF BRAKE LIGHT SWITCH OR BRACKET LOOSE AND AWAY FROM BRAKE PEDAL BRAKE LIGHT WILL STAY ON.IF BRAKE LIGHT SWITCH INTACT BRAKE LIGHT SWITCH NEED REPLACING.WHEN REPLACING BRAKE LIGHT SWITCH OR IT NEEDS ADJUSTING MAKE SURE BRAKE LIGHT SWITCH PLUNGER TOUCHES BRAKE PEDAL ARM WHEN YOU RELEASE BRAKE PEDAL BRAKE LIGHTS SHOULD TURN OFF.

Check the brake light switch, it is down on the brake pedal lever, you can dis-connect the wire connector at the brake light switch and check for broken wires at the connector, and then jumper the connector with a paper clip, if the brake lights come on then replace your brake light switch.

There might be more than one switch attached to the brake light pedal lever, the brake light switch usually only has two wires going to it when there are two switches.

If there is no problem with the brake light switch then you can suspect the turn-signal switch to be at fault, as all of the running lights, turn-signals, brake lights, and hazard lights are all ran through the turn-signal switch. You can also try stepping on the brake pedal and wiggle around the turn-signal switch and see if the brake lights flicker or come on.

It is most likely your brake light switch. The wiring from the brake light switch goes to the turn signal switch. When the turn signal switch is centered both brake lights are connected, unless the switch is faulty. When the switch is to the left only the right light is connected to the brake light switch and vice versa. A bad switch can cause all kinds of problems with the brake lights as well as the turn signals.
To replace, locate the brake light switch at the top of the brake pedal (on the mounting bracket). Unplug the connector. Loosen the locking nut and remove the switch. Install the switch and adjust the height so the switch activates at the right position. Reconnect the connector and check for proper function.
