Check the switch at the brake pedal, it is what makes the brakes come on, it may be malfunctioning.
The brake relay switch is bad.
Probably a blown fuse.
Fuse for parking lights probably blown.
It sounds as if you have an electrical problem that needs to be checked. You may even have the wrong fuse for your brake lights.
The problem might not be a fuse. There is a switch which activates the brake lights when the brake pedal is depressed. This switch is usually mounted under the dash, near the top of the brake pedal lever. Insure that this switch is free to move physically, and test it to see if it is switching electrically.
check fuses & brake lights switch located on brake pedal
check the fuse, brake lights have their own, & check the brake switch at the top of the brake pedal
Check the fuse. Then check the wiring.
It could be a blown fuse. Tail lights and brake/turn are on separate fuses. Apparently there is not a ground problem since brake/turn works OK.
i replaced a brake light bulb in my 2001 golf now none ofthe brake lights are working ! i can not tell which fuse is the one for the brake lights ! please help ?
Check the fuse for the headlights. It is probably open.
There should be a fuse for the brake lights. If the fuse is good always check the ground wire.
