Mine had a broken switch on the break pedal. The switch was cracked and gave intermittent break light circuit failure. Replaced switch. Works fine now.

I have a 2009 Chevrolet Colorado and my rear brake lights are not working. My brakes work but not my rear lights. Tried replacing bulb but that wasn't problem. Hopefully someone has some answers.


if all the brake light bulbs are ok it could be the brake light switch which is normally on the brake pedal hope this helps.also check if theres a fuse for your brake lights some vehicles do.

I have a 91 ford f150 and the brake lights wont work and the rear right blinker is dim. Can you help me?


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.

I have no brake lights an my 1998 Chevy Venture Van everytime I put a fuse in it blows soon as I hit the brake pedal


You most deffinatly have a dead short, thank god for fuses. You will need to chase all realated wires , look for a bare spot in a wire thats touching something metal. Good luck

Driver side brake light wont work, its not the bulb!! or the fuse.


sprinters are really picky with the type of brake bulb used.. make sure it is the same make as the others.. Also the circuit boards are known to corrode together.. however usually this will set off a warning light.. other wise i would say wiring issue on that side.. let me know how it works out

Little yellow warning light goes on. All bulbs


you most likely have a wrong brake light bulb. if the bulb is a different wattage it will still work but the bulb warning light will still illuminate.

Key wont lock doors. Cannot lock doors from inside car either.


hey doug, if you have excessive resistance in the brake circuit the warning will come on. I would first check the brake light sockets and bulbs to make sure they are not corroded or the bulb turned dark. If they are ok, then I would replace the brake light switch located above the brake pedal. you will have to remove the driver's lower trim cover to access the brake light switch.the circuit is seperate from the central lock system.

Left rear brake light stopped working but bulb and fuses are OK.


take the bulb back out have someone sit in car apply brake get your self a circuit tester and check to see if this circuit is carrying efficient 12 volt current! some times in cold weather these bulbs get hot with long period of breaking and when released condensate and rust begins and you get what you have perhaps bad socket! this would be a ideal location to begin and probably end,
