Check your fuses. See owner's manual for location and assignment of fuses.
Start by checking your fuses. Then bulbs. Then switches in that order.
Check the alternator capacity.
It is possible it is the body control module, I had the same problem except my brake lights worked.
check back pads and also check break fluid.
How do you replace brake lights
It depends on the vehicle but in general you would have one fuse for the signals and one fuse for the brake lights.
Brake lights
Fuse 7 controls the brake lights. It should be a red 10amp fuse.
Blown fuse
Brake lights and turn signals are on a separate circuit from the tail lights. Tail lights are on the same circuit with the dashboard lights. If the dashboard lights aren't working either, check the fuse. If they ARE working, check the headlight switch.
Could be the brake light switch or fuse.
i have tail lights but do not have brake lights nor do i have turn signals. i have replaced brake switch and all bulbs
