What fuse operates the brakes?

If the dash lights are on the same circuit as the park lights. Chances are if no dash lights... no park lights. Unless the dash light dimmer switch is on the low position. Check park light fuse. If no brake lights... which are on a different circuit and you are sure the bulbs are ok check brake light fuse. If fuse ok, unplug brake light switch at brake pedal and cross the terminals with a jumper. If brake lights work, the brake switch is faulty. If still no brake light operation suspect a wiring issue

The bulb is most likely bad. The fuse operating the third brake light also operates the main brake lights. Have a good one.

Check fuse.
Check if center light works.
Check for power at light sockets.
Check brake light switch.
Manipulate the turn signal lever.


- To check the brake light fuse, open the passenger door and remove the fuse panel cover that is located around the corner from the glove compartment. On the back side of the fuse panel cover there should be a fuse location chart. The brake light fuse is #23, located in the socket that is dead-center among the mini fuses. I believe it is supposed to be a 15A fuse. Confirm the condition of the brake light fuse and replace if necessary. If the fuse fails again, determine and correct the cause.
- Also, see if the center brake light is working properly. If it is, then the brake light switch is working. If the center light is not working, the brake light switch is suspect. That switch is a spring-loaded plunger switch that is of the "normally closed" variety. In this application the switch is usually held open by the brake pedal arm, except when he pedal is depressed. Then the spring within the switch holds the contacts closed so that the brake lights will operate.
That switch is located under the instrument panel. Look for a push-button switch that is contacting the brake pedal lever. If the car has cruise control there will be two switches, one above the other. I believe that the lower of the two is the brake light switch.
- With the brake pedal depressed, see if you have power and ground at the brake light sockets. One good way to confirm that is to remove a brake light bulb and connect a 12v. test light across the contacts in the socket.
- An operating center brake light combined with no power to the 12v+ terminals at the left and right brake light sockets could indicate a defect within the turn signal switch. If you get to the point where you suspect a defect there, try applying rearward pressure on the turn signal lever and see if the brake lights work then. If that procedure confirms that the defect is within the turn signal switch, you can replace the turn signal switch. Or you could try my trick which cost me less than a dollar and has worked for years.
See attached photo.

Spacer (piece of rubber tubing?) is used to apply rearward pressure on turn signal lever. I have not disassembled the switch assembly, but evidence suggests that electrical contacts inside the switch depend on the mechanism being positioned properly. If the internal positioning device failed (perhaps the lever was pushed forward) then an external device can be made to hold the lever and switches in proper location.
If you attempt this repair, consider applying some lubricant as deemed necessary.
Good luck.

They use the same bulbs in the back.
Check the light sockets and wiring for shorts to ground.

Check fuses first. Should be a fuse labeled 'Stop' or 'Brake'.

If fuses are good, climb under the dash and look at the brake switch, it's high up on the brake lever. Make sure it is operated by pressing in the brake pedal.

check for a bad brake light fuse! if not the fuse, the brake light switch operates brake lights and if bad you will not be able to shift it out of park, as well as the brake lights not coming on.! because you have to put foot on brake to do so. if bad switch, it wont let it out of park. it could be just out of adjustment also!! good-day !

I am a liecenced mechanic. Start addressing your problem by checking the brake light fuse in the main fuse panel. See the owners manual for location. Main one is under the hood. Secondary panel is on the passenger side kick panel area or in glove box. Replace the fuse if blown. If fuse is o/k check brake pedle brake light switch adjustment. If switch is adjusted properly, check rear brake light bulbs next. If they are o/k check for power at the bulb socket with a 12 volt test light with brake pedle depressed. Light should light. If it does not replace brake light switch and check operation. If problem is not repaired buy a repair manual or bring to a technition for diagnosis.

Have you checked the fuse for the brake lights? if not do so and then check the brake light switch mounted to the brake pedal, then check bulbs. Even new bulbs can go out!
Check the manual for fuse location for the brake lights.

CHECK THE BRAKE LIGHTS HAVE A ASSISTANT OPERATE BRAKES TO SES IF BRAKES LIGHTS WORK WHILE APPLY BRAKES BECAUSE BRAKE LIGHT SWITCH DEACTIVATES THE CRUISE CONTROL.IF BRAKE LIGHTS DONT WORK.CHECK FUSE IF BRAKE LIGHT FUSE IS GOOD.THE BRAKE SWITCH IS BAD OR HAVE A OPEN FROM FUSE BOX TO THE SWITCH.IF BRAKE LIGHTS WORKING.THE DEALERSHIP HAS TO SCAN VECHICLE BECAUSE CRUISE CONTROL SYSTEM IS CONTROLLED BY A SERVO MOTOR MOTOR, BRAKE SWITCH ,CONTROL SWITCHES ,SPEED SENSORS AND RELAYS. SEE YOU HAVE TO HAVE VECHICLE SCANNED YOU HAVE TOO MANY CONTROL DEVICES.

If it's the brake lights, you may need to adjust your stoplight switch under the brake pedal bracket. If it's the taillights, then you will need to trace and diagnose it. Which lights are staying on and which circuit does fuse #23 operate?

Thanks,
