Check and replace the brake bulbs first, and if they are still not working examine the fuses, switch and wiring.
How do you replace brake lights
Check and make sure you have the correct bulb. The turn signal/brake light is a dual element bulb and if you have a single element it does not work properly.
Fuse, wiring, bulbs
No brake lights but turn signals work? Turn signal switch brakes route through it.
The most likely cause is a bad brake light switch (if none of the brake lights illuminate) but if its only one of the brake lights, try changing the bulb. Even if they still work as running or turn lights because they have a double filament and may still work partially, but not as brake lights.
To be more specific, the ground wire must work and the bulbs, fuses, etc.. Or the back up lights and turn signals and brake lights wouldn't work? Right? Could it be the back panel...and still let the brake/turn/backup lights work? I need help fast. Thanks!
The turn signal switch overrides the brake light circuit while the turn signals are on. If the switch is damaged or worn out the brake lights won't work.
Look for a fuse labeled TAIL LIGHTS. There are 2 separate circuits, one for brake turn and flasher and the other is for tail lights.
Check the fuses.
either dimmer switch or blown fuse If you are saying that the tail brake lights are working but the third brake light is not....It may be a defective turn signal switch in the steering column.
A defective brake light switch could cause the problem. Also a defective turn signal switch could also. The brake lights work through the turn signals. It cancels the brake light so that the turn signal can work.
Fuse 7 controls the brake lights. It should be a red 10amp fuse.
