All the lights stopping at the same time is not likely a fuse, it would be the brake light switch, the brake light switch is over the brake pedal near top of brake pedal arm under the dash. To test take a 12 volt test light ($5.00 at any auto parts store) and see if both side of the switch light the test light when the brake pedal is pushed, one side is hot with 12 volts without pushing the brake pedal down. The fuse location is in the owners manual but I am 99% sure that isn't the problem.

Check System Fuse - A fuse is used to protect the brake light circuit from amperage overload. If the fuse has failed it will not allow the electrical current to continue to the brake lights. To check the fuse, first locate the brake light system fuse in the fuse panel which is either under the dash or under the hood in the power distribution center. Connect the test light to a ground like an engine or dash bracket and turn the ignition key to the "on" position. Using the test light probe both sides of the fuse. If the test light illuminates on both sides the fuse is okay continue onto the next step. If one side of the fuse illuminates the fuse has failed and needs to be replaced. If the fuse fails as soon as it is replaced or when you apply the brake pedal the brake light electrical circuit is shorted to ground. Rarely a system short can occur, a car repair manual is needed to find the wiring schematic for the brake light circuit. Once the brake light wiring has been located inspect and repair as needed.

Check Brake Light Bulbs - All cars have three brake light bulbs that create the brake light illumination affect. If all of these brake light bulbs fail no brake light operation will occur. I know what you're thinking, you might say all three brake lights at once? But in reality one brake light went out at a time and you did not notice. People only tend to notice something when they almost run into the back of your car to help persuade them to inform you the brake lights aren't working. Remove any of the brake light bulbs to confirm the bulb is okay or burned. After the bulb has been removed inspect the filament and replace if failed. If the brake light bulbs are okay continue to the next step.

Checking the Brake Light Switch - A control switch is used to connect the brake light electrical circuit. This switch is located near the brake pedal lever. Basic switches have just two wires, power in and power out to the turn signal switch. Use a test light that is grounded and with the key in the "on" position test for power at one side (wire) of the switch, then press the brake pedal while testing the opposite side (wire). It should illuminate the test light, if electrical power is connected through the switch go to the next step. If no power is detected through the switch the brake light switch has failed and replacement is required. If your car is equipped with more than two wires integrated into the brake light switch a car repair manual is needed to locate the proper brake light circuit wiring.

CHECK BRAKE LIGHT SWITCH FUSE.IF FUSE GOOD. POWER GOING TO BRAKE LIGHT SWITCH.REPLACE THE BRAKE LIGHT SWITCH.

Hi,

This is caused by one of two things.

1) Blown fuse - check the fuse box for the fuse that controls the brake circuit. Replace as necessary.

2) Bad brake switch - If the fuse is not blown this indicates a faulty brake switch on the brake pedal itself. This will need to be replaced.

Thanks for using FixYa.

First ensure the bulbs are fine.

Check and replace the fuse in your fuse box.

If it keeps blowing after replacing the brake lights fuse, then there is a short on the wires, you need to check wiring.

If fuse is ok and there is no brake light check wiring to the lights, there is a broken connection or an open wiring to the brake lights.

Note: brake lights are usually not dependent from tail lights, they have separate wiring.
